Gasoline - Hesitation :: 1998 - Hesitates Only Sometimes / Loses Power While Driving
Jan 7, 2015
I have a 1998 Honda Civic LX that was converted from automatic to 5 speed. It hesitates while I drive, only sometimes. Normally it does it when I am pulling off from a stopped position or when turning the corner and then accelerating. I will have my foot on the gas, but it won't gain speed unless I hold in the clutch and rev up the engine then it will pick up speed and go fine. Then sometimes it also hiccups while driving without accelerating, I can feel the car jerk a few times and start to loose power.
I will need to down shift to third, or most often 2nd gear and rev it again to gain power and to pick back up speed. Things done to it since i bought it only a few months ago by the person (who is a mechanic) I bought it from: oil change, fuel filter changed, Lucas gas treatment added (by me), new exhaust system installed, starter replaced. I am nervous that it may be rear-ended, or t-boned in heavy traffic. Should i have the fuel filter checked?

My 88 "Rosie" has been having problems for months. It hesitates, stalls, and sometimes backfires. This is an intermittent problem, though it is happening more often lately. I took it to local auto shop and their computer showed Rosie was throwing a misfire code as well as a lean code. I took it 3 months ago, and I took it last week, got the same codes. The lean code led me to check the fuel pressure. I did and while it should be healthy 48-55 psi, I got 48 for awhile then 15 PSI! Now I'm thinking fuel delivery. I started with the filter. Sure enough it was dirty. Weeks later, the problem persists. I replaced the fuel regulator (ok, mostly because it was cheaper than the replacing the fuel pump, which I really didn't want to have to do.) Still, no luck, so I finally caved and spent $200 and 12 hrs dropping the tank to replace the fuel pump. Guess, what? Still no dice. I'm still getting the hesitation and the misfiring. I haven't put the fuel pressure tester back on it (been busy) so I don't know if the pressure is still low or if these other things are even related. I thought my logic was infallible. Let's face it, there's a finite number of parts that control fuel pressure. I'm running out of parts to replace. Where did I go wrong? The only thing I can think of that could still do it is perhaps the fuel pump relay? I dunno. Would it work off and on or fail completely? I'd love to get some opinions on this.

1998 discovery. Replaced fuel pump, crank shaft sensor, battery is good, had tune -up. Driving on highway and car just loses engine power, still have radio, lights, etc. Pull over and start it right back up. Drive about 15 minutes more and it happens again. Starts again. Then it does it again, but now won't start. Clicking sound in dash on passenger side. I leave it sit for 2 days. Starts right up, then rpms start revving then stops and dies. I have had every diagnostic known run, no codes coming up. I have had local mechanic keep it for days to drive it. He is also at a loss. I am REALLY tired of replacing random parts to no avail. Not to mention the $$ I have spent.

My manual 98 Honda civic hatchback has 435,000 miles. But for the past 5 months, it has had a reoccurring problem: it loses power at unpredictable times while I'm driving. The gas stops responding and the check engine and battery lights come on. Have to pull over, turn the car off and usually have to wait on the side of the road 5 minutes before it will start again. Lately, it can take as long as 15 minutes. Sometimes, it will restart immediately or after only two minutes.
So far, trying to get at this problem, the car has gotten: new battery, new alternator, new spark plugs, new coil, new distributer, new ignition switch, diagnostic testing (that indicated the coil [replaced] and the catalytic converter). There does not seem to be any consistent environment that goes along with the car turning off while driving. It happens regardless of how full the gas tank is and regardless of the weather.It's pretty bad to be going 70 on the highway and suddenly have to throw on the flashers and pull over... especially when there is no shoulder because of winter weather. What this is? Or is the car just old and tired?

My 2006 650i loses power under moderate to heavy acceleration. If I accelerate from anywhere over 2500rpm, it will accelerate then the engine rpm will drop suddenly by 500-1500rpm, and then will continue to accelerate again from this lower rpm. It only seems to happen once each time I punch the pedal. The car does not throw any codes. I have had the dealer and Dinan Performance examine the problem and they have not been able to isolate the problem. They have run vacuum leakage tests, fuel pressure tests, and may have checked the throttle position sensor. This really takes the fun out of driving this car. I have about 50K miles on it.

I have a 2000 Ford Focus SE with DOHC that is losing power and sputtering when it gets hot after driving for 30 min or more. If I shut the car off and right back on going down the highway it will be fine for 5-10 min and then start sputtering again. If the car is not hot this does not happen and I have a new fuel filter and coil pack as those are the two main things that I could think of. I have seen intake valve seat and fuel pump as the two most common fixes with similar circumstances.

While driving my 1998 Chevy Prizm, my car lost the ability to accelerate but the car never lost power. I managed to pull over and let the car run for a bit before trying to accelerate again..the car only got up to 30 mph and wouldn't go any faster.....after a couple of hours the car run okay. What could be going on? I got new spark plugs, oil change, and an idle air control valve........

My '98 Tacoma automatic has had a intermittent hesitation for 5 months. I've had it to 3 mechanics who cannot get it to hesitate when they are driving it. I left it for 2 nights at the last auto shop and let them drive it when it's cold and they couldn't find anything wrong with it. It hesitated 3 times this afternoon as I was driving it home from the shop.
Everybody has told me to wait until it gets worse to bring it back to be fixed. I have a new catalytic converter, o2 sensor, fuel filter and none of that has worked. The check engine light has come on briefly once, but went off before I could get it diagnosed. What I can do to get it diagnosed and fixed before I get stranded somewhere?

My car (Nissan 1998) runs normally for miles. Then sometimes it just starts lurching while in motion when the gas is depressed and looses speed, as if not getting fuel. Previous times it dies after this. The last time I was on the highway going 70 and I pulled over before it lost power and died completely. Just had new brakes installed, new distributor, all new belts, and an oil leak fixed by a mechanic.

The last couple of days with the temps in the 50's, my 2000 F550 with a 7.3, will start normally and idle fine. When I try to drive it, I get less than a quarter mile and it just looses power and will die.
If I flutter the pedal, sometimes it will keep running, very poorly. And when it does this, it is putting out blue smoke. After it does this, it will run fine. Just like nothing is wrong.
What do I look for, or is this normal. I have had the truck since last October and this is the first time it has acted like this.

My 3.5 intrigue seems to stumble while driving it. It feels as it the engine is stumbling or loses power for less than a second and it will do this a few times in a row and will be fine for awhile and then repeat itself.
This can happen while cruising, slow acceleration or at a stop light. I don't really notice it under harder acceleration. When it does happen i do notice that the rpm's drop a very slight bit.

Jeep runs fine for days and then it will have a bad day. Loses power for a minute or two and then revs back up. If you stay on the gas it acts like it wants to stall something makes a loud banging noise under the jeep and then it takes off only to do the same thing in 2nd gear 3rd gear etc. Would o2 sensors try to shut it down? Throttle position sensor?

While driving my lights flash like a strobe light and I can see this at night. The. The car loses electrical power for 1 sec and then all okay. In the morning when I start the car I get ESP errors whilst idling, I then turn the car off and try to start it again and everything is completely dead!
When connecting jumper cables then trying again it works, the. I don't have a problem for about 3 days the. The same thing happens. Battery is brand new, had it at the dealers and errors are intermittent electrical errors but doesn't say where.

I have a 2005 F-350 Lariat, FX4, CrewCab, with an 8ft Bed if any of that matters. Currently sitting at 191,000 miles and 4,500 Engine Hours I just started running into some issues that I cannot figure out. To start with here is a list of all the mods and prior maintenance that I've done to my truck over that last 6+ years that I've owned it.
I purchased the truck in 2010 and had no issues whatsoever for the first 3 years.....then it all started. While pulling a camper home from vacation "still bone stock" the truck overheated and by the time I realized it it was to late. I ended up blowing a head gasket cracking a head and blowing a hole in my coolant reservoir from the heat & compression of the engine in the coolant system. So to the shop it went.
All of this was done at the same time at just under 4,000 engine hours:
1) Both heads were sent out to be pressure tested "which is where the crack was found", so 1 replacement head and the other trued up and tested by the machine shop
2) All 8 injectors replaced with Airtex/Wells New/Reman
3) ARP Head Studs
4) BPD EGR Cooler
5) New Stock Coolant Reservoir
6) New Stock Oil Cooler
7) Motorcraft Coolant & Oil/Oil Filter Change
8) New Serpentine Belt
After getting the truck back I installed some upgrades that I had wanted but didn't want to do until I had head studs. 4" Turbo back Diamond Eye Performance exhaust, Bully Dog GT Tuner with an EGT Pyro, coolant changed to Caterpillar ELC, Sinister Diesel coolant filtration system, new Optima batteries "I hated them",
Forward a year with no problems I had a crank but no start. I ended up having a bad IPR. A buddy rebuilt the turbo since I had it out and it was leaking. He apparently did something wrong because it took its own life sometime after. So a brand new stock Garrett Turbo with a Wicked Wheel 2 & I changed the IPR "don't remember the brand." Also replaced the factory paper air filter with a cleanable one from AFE that fits in the factory cold air intake.
Little more time and I started to have some overheating issues again, luckily the Bully Dog was monitoring and I had alerts set up so I caught it way before it caused any serious damage. Turned out the fan clutch wasn't working. So I replaced the Water Pump with one from dieselsite.com that has a steel impeller, also replaced the computer controlled fan clutch with a 7.3L mechanical fan clutch and an adapter from BPD.
After that the batteries I hated were replaced. I installed Oddssey Extreme 950CCA ones, a new 185A alternator from FICMRepair.com as well as the complete battery wiring interconnect kit. Did the blue spring upgrade. Replaced my FICM with the BPD 6 phase at 54V setting. Also I changed my starter to an 6.4L Ultima one from O'Reily Auto to bring me up from that slow crank of the 6.0L at about 150RPM to the 225RPM of the 6.4L.
So now on to the current issue. This has happened in the last month and may be related to the issue. I had some small coolant leaks and wanted them fixed. Pressure tested the system & found the radiator and timing cover gasket leaking. I installed a new stock radiator and lower radiator hose. Had the shop do the gasket and a serpentine belt due to cleaners being all over it. During replacement of the timing cover gasket my mechanic found that the LPOP gears had some damage as if something had be in there at one time. Not sever damage just minor. LPOP replaced with brand new one from Ford.
After I got the truck back it was fine for 2 weeks, no leaks or any problems whatsoever. Then I noticed a hesitation as I was leaving work at idle. You could see the RPM's moving up and down by about 50 as it sat there at idle. It got really bad and eventually stalled on me. It fired right back up and ran fine after. I was thinking water in the fuel or just maybe old fuel because it was kinda old and I was at 1/4 of a tank. I went and filled up and it ran great all the way home. Day or so later same thing. At idle you can see the RPM fluctuating and while driving it feels like it has no power at times then it goes away and runs fine. So I changed both fuel filter with Motorcraft ones and put in a new oil filter. It is the Wix brand but I've be running it for years with no issues, one was also in it way before this issues started. The oil has about 2,000 miles on it currently. I verified fuel pressure at idle to be at 70PSI. I tried unplugging the ICP at idle with no change in the hesitation. So I plugged in my SG2 and started to see if I could see anything out of the ordinary.
OAT - 60 Degrees F
KOEO Engine Cold - FMP - 54.5V, ICV - 0.25V, ICP - 0, IPR - 14.9
KOER Engine Warm - FMP - 54.5V, ICV - 0.82V, ICP - 576, IPR - 23.5
Cruise at 40MPH - FMP - 54.5V, ICV - 1.14V, ICP - 965, IPR - 32.9
Cruise at 50MPH - FMP - 54.5V, ICV - 1.42V, ICP - 1,190, IPR - 38.0
Cruise at 60MPH - FMP - 54.5V, ICV - 1.27V, ICP - 1,143, IPR - 37.2
While driving this issue comes and goes very randomly. The only parameter I notice changing alot is the IPR. It jumps around a lot and sometimes it will go to 85. I know that this isn't a good thing so I am going to change the IPR later today or tomorrow. I already had a brand new Motorcraft one to put in, plus at the very least I want to look at the screen. I had read somewhere that there could be air in the oil system and that if you run at a high RPM it can remove this air. I never seen any bubbles or anything on the dipstick. My brother ran the truck for me at 3,000RPM for 5 minutes. No hesitation during the test but he didn't have the SG2 plugged in so I don't know the parameters during the test. I thought that it worked but then it came back after a few miles of driving. The above parameters are from this mornings drive home from work.

5.0L V-8, Electronic Fuel Injection, 79,000 miles, 2 WD, 4 speed manual. I'm the original owner.
If I drive it 4-5 miles on secondary streets (25-40 MPH) it shuts off without warning after 10 minutes and will not restart without a 20-30 minute wait. If I drive it 2-3 miles and park it for a couple of minutes it will not restart without waiting 20-30 minutes. Checked engine water temp gauge and it is normal.
The local mechanics found no spark when it failed at their garage. They replaced the ignition module on distributor. This did not fix the problem. In their second attempt they replaced the coil. Still the same problems persists and the mechanics are stumped.
It's like something in ignition package heats up after 10 minutes and either sticks open causing no spark or closes shorting out the spark if that is possible. What is causing this and how to fix it.

My AWD 1996 Subaru Legacy Station Wagon suddenly loses power while I'm driving......

My mercury Monteray 2004 model, suddenly loses power while driving. This has happened both on the freeway and on the local roads. I then have some how driven it to the shoulder. After stopping for couple of minutes when I restart the car it works and I have been able to drive it. I have taken it 3 times to the dealer and he has not been able to identify the problem. I am extremely scared of driving the vehicle. We even had flight recorder from the dealer on the vehicle and recorded the incident 3 to 4 times and still the dealer has not been able to figure out what the issue is. They say that they have tried several times and have not been able to recreate the issue. They say that they have tried to recreate the issue with a computer attached so they can record the issue when it occurs. But apparently they have never been able to recreate the issue. Other wise the van is in excellent condition. What could be the issue? We have not been able to use the van for over 6 months and do not know what to do with it.

My Solara is running horribly. Its acting like the fuel pump or regulator is acting up as it loses power while driving and pumping the pedal usually does nothing. Its so bad that I cant drive it since top speed is about 10mph. If I just slightly touch the gas while driving I can get up to speed a little. It stalls when idling often too.
One thing I notice is if I stop driving for a while (with engine running) sometimes I can then drive away and the engine seems almost normal for 1-2 mins with lots of power. When the engine is cold it usually drives for 2 mins before these problems start.
This is a 2005 Solara. 4cyl 2AZFE gas engine - automatic - all stock - roughly 100,000 miles on the clock.
Its giving 2 codes: P0172 and P2196
I have looked up these codes and from reading I thought to try replacing the MAF sensor - no difference.
It feels like I'm driving a car with a bad carburetor again - really bogs out and laggy and sometimes even sounds like its backfiring slightly.
A bit of history:
- a few months ago I got the P0031 code so I replaced the upstream o2 sensor and all was good for a month or so.
- then about a month ago I got the P0136 code so I replaced the downstream o2 but it was starting to run badly before I could install and when I replaced it there was no change.
- last week I was surprised to see codes P0113, 172, 300, 301, 302, 303, and 136 but found that the battery terminal voltage was 10.5v so I replaced battery and those codes do not come back now.
- I'm thinking that due to the bad battery maybe the o2 sensors were not a problem? The upstream replacement made no difference (though it was running fine-just the CEL came on), and the downstream replacement made no difference (runs badly before and after).
My guess is fuel pressure, regulator, or injectors but its just getting too expensive to try.

My 2000 Toyota Corolla, automatic, loses power when I decelerate after driving for a short distance when I am entering the freeway and trying to accelerate on the ramp and then into traffic. The car never dies or turns off, but loses power and "coasts"; as I coast along and try to get out of the traffic, I press the accelerator pedal almost to the floor and within 5-10 seconds the car will roar to life and accelerate like it's getting all the power it needs. That's usually the end of it for that day...however, there is often some hesitation as I continue driving. This doesn't happen all the time, but almost always when it's been outside all day and the temperature has been at freezing or below...usually when my car has sat all day while I'm at work. My mechanic hasn't had time to look at it yet but has suggested perhaps a bad switch of some kind or maybe a dirty switch. Also, this may be unrelated, but often before this happens the brake light will sometimes come on and stay on...even though the brake isn't on, nor has it been on while parked. This never has happened in the mornings after my car has been in the garage all night.

This happened twice this month and each time was after driving and then turning car off to go into a restaurant to grab food real quick. Start car up back out, put car in drive and before getting out of lot loss of power followed by car stalling and only battery indicator comes on. Car starts right back up and seems to run fine. No CEL.....? I'm assuming I cannot scan car if no cel is on. I was thinking cam position sensor or fuel pump. I'm about ~1100 mi over for oil change which I am getting Monday.

I have a 1986 Honda Accord Hatchback Lxi, 180,000 miles, automatic, one owner, always excellent care (very recently new spark plugs, new air filter, new oil and filter, and several years ago new Pirelli tires). Lately, while driving, it intermittently loses power, like it's going to stall, but never does. I accelerate to recover. Years ago I used to hear about vapor lock. Last week I took it to a Honda dealer. They had no diagnostic machines for "old" cars and had no clue what was causing this. Most of the time, the car drives beautifully, but it's scary thinking it's going to quit and I'll be stranded on the side of the road.
