Ford :: 1999 V8 - Skipping / Missing / Hesitating Then Jerk Forward All At Once
Jul 31, 2012
I drive a 1999 Ford X V8, 189,000 miles and it's been a great car. Lately tho, and in particular when the temperature is above 90, it begins to miss, hesitate, then jerk forward all at once. Some times, when the accelerator is depressed, NOTHING happens. No response form engine at all. This can last three seconds of so, then the car will lurch forward. I have done a 180,000 mile complete tune up, a, fuel induction system service, replaced the Mass air flow sensor and checked all points, plugs, new air filter, etc. Still, the problem persists.

We have a 2001 Santa Fe. Very recently it began hesitating when put in gear going forward or reverse. Once the gas pedal is pressed, there's a delay of up to 2 seconds as RPM climbs, then the vehicle jerks into gear. It seems to run fine otherwise. Mileage is approx 128 k. Maintained very well by the same mechanic until very recently. Internet searches have gotten answers of use fuel additive, install some computer patch, fix an oxygen sensor, change tranny fluid and flush tranny, rebuild tranny.

I own a 1987 Mitsubishi Montero 2-door, 4x4, vin # JA7FJ23F9HJO30272 with a 5 speed manual transmission. It's powered by a family 2.6 T2FFC3 engine with CID 1.55.987.
My problem occurs quite sporadically, sometimes after driving 100 miles or so. Then, the engine starts missing as if you were turning the ignition off and on very quickly. Most often I have to limp back home by getting spurts of acceleration along with skipping.
Some technicians say the bushings are worn out in the distributors shaft housing and some other technicians state it may be a carburation problem. However, I am desperate for a solution to solve my problem, and possibly better my fuel economy to more than 12+/- miles per gallon.
Is this a common problem of these vehicles with high mileage? Do you have a solution to resolve my problem? My vehicle has 132,059 miles as of this writing.

I'm getting some vibrations from my '06 2.0T. The car tries to jerk forward at a dead stop, RPMs jump about 100-200RPM. It kinda feels like stalling a manual transmission, only milder. The car is burning a bit more oil than it should.
Many claim it could be a faulty PCV Valve. Since I'm a little on the broke side and my car is out of warranty, what should I look for to tell if the valve or the hose is faulty?

I have a 2002 Pontiac Aztek with about 170,000 miles on it. About 3 weeks ago, it began having problems when I would hit the gas to speed up. It would hesitate, and then jerk forward and go. Then about 2 weeks ago, I was driving on the highway and the engine just suddenly stopped - as if I had turned off the key.
There was no warning, no sound, nothing. I kept hitting the gas the whole time and it started up again after a minute. I replaced the fuel filter and it ran well for a week. Then it happened again, but this time the engine completely turned off and I had to turn the key to restart the engine. The engine started with no problem.
I tried to drive to the mechanic, but the engine stopped & started again on the way, so I ended up having it towed. It is not driving roughly or idling roughly, it doesn't make any strange sounds and no warning lights come on. When the engine stops, all electrical components are still working (lights, radio, etc.). My mechanic appears to be stumped. What could be causing this?

I have an 01 Buick Regal GS, 82k miles. When I baught the car it had 80k miles but had been sitting for a while. I put in a new battery and changed the oil as soon as I got it. When accelerating the RPMs will go up but the car won't accelerate as fast. The RPMs will drop and the car will jerk forward. And then accelerate better after it is warmed up a bit. I thought to give it some time and maybe it will go away. 2k miles later it is still doing it. What it could be?? I would like to see if I can fix it myself.

I recently purchased a 2005 Camry XLE V6 (100K miles). Its in great condition and no issues except I am observing this:
-> When I come to stop (like at a stop sign), just before coming to complete stop, there is a slight forward jerk. When I come to stop slowly and smoothly, there is no problem.
the faster I come to stop the more severe is the jerk. I tried to search for answers on the web, one possibility is bad solenoid in the transmission.

I have an 03 vw Jetta 1.8t with around 100,000 miles and I recently ran into a problem with the car jolting, or slipping when I get on it hard. And also when I'm sitting at a stop light it will jerk forward like it wants to go. I've tried a few things like cv axels and some other things but I'm just hoping it's not the tranny.

I have a 2011 Chevy Impala. When accelerating from a stop it will frequently stutter then jerk forward. The first time this happened I thought someone had rear-ended me.
I've been to the dealer several times about this however they say they cannot isolate the cause. More importantly I can't seem to get the vehicle to repeat this problem when I've brought it to the dealership.

I have an automatic Jetta and just hit 130,000 miles. Recently, my car would randomly after I turn it on and put it in drive, the car would jerk forward and make like a popping noise. Then the car drives fine as usual. As if the gears are slipping? Is this a sign that my transmission is going out? What else can cause this? What should I do?

Reverse band broke in my C4, I took it apart enough to get the rear band out and then reassembled. Everything to my knowledge was seated correctly and the front pump seated flush with the case when I reinstalled (which is supposedly a sign that it is all seated correctly). I adjusted the bands to spec and replaced the vacuum modulator and torque converter. These were the only things replaced besides the reverse/low band. Vac modulator was replaced to original (yellow band) as I was running an adjustable before. TC was replaced just because I did not the last time I had the trans rebuilt in 2003....decided to go ahead and R&R.
I got everything assembled, filled up with fluid and no leaks. I start it up and once i finished topping it off, the truck moves forward in every gear... including park! It also seems that I'm missing a shift detent. I have P, R, N, D, 2 but no 1. I disconnected the shift linkage and tried manually shifting from the trans and have the same issue.
I did not open up the valve body, just unbolted and replaced. When you start it up, it doesn't jump forward (while in park) but when you rev it up it sounds like the motor is under load. I've consulted my Haynes C4 book and an extensive google search and no way...

Mostly occurs at high speeds and climbing hills. Could it be a transmission problem? Or a fuel pump?

A couple days ago, my Excursion started skipping 2nd gear when driving in D. The RPMs will go up to 3500 or so before slamming into 3rd gear. Shifting in all other gears works fine. However, when manually shifting through the gears (1, 2, D), it finds 2nd gear and shifts fine. I am mechanically inclined when it comes to engines, but not an auto trans.

I have a '99 Ford Taurus that was hesitating and sputtering while driving. I had the fuel pump replaced about a week ago thinking my problem was solved. Lo and behold, while driving about 50mph and trying to pass vehicles, my car started doing the same thing. It acts as though I have bad fuel or there is dirt somewhere that is entering my gas line.

I have a 99 f250 that seems like it has a bad coil, under a load it starts surging or bumping ( like it has in the past and I found a bad coil), I went through and unplugged each coil one by one while idling, couldn't find a bad one, so I bought a new coil and went through and rotated the coils, nothing worked, no check engine lights on.

just bought a 01 f350 v10, 40,000 miles, plowing beast, anyways when taking off truck seems sluggish, give it more gas as its fine. At idle there appears to be a skip. There are no check engine lights on, could it be the coil pack or even maybe fuel problem? Have done plenty to this beast to get it close to perfect and this motor issue is it.

I have a H&S mini max. Controller and have installed the mild download and run on the street setting for every day and tow setting while towing my fithwheel, when I just took it out for a test drive towing the fit wheel going up hill it kept shifting up and down which sure felt like 3rd and 5th because rpm would go from about 3500 to 1500 back and forth so it sure felt like it was not hitting 4th, could this be a controller issue?

I have a 2002 7.3 160k miles and recently it has been hesitating while cruising along at 35mph roughly. In park right off idle the engine does shake but if i give it a little more pedal the shake clears out. Not sure if that has anything to do with my issue but im just throwing it out there. Anyways cruising down the road the truck will hesitate almost like its not getting enough fuel the engine bogs then picks up then bogs and picks up but it i give it more pedal the truck gains speed and the issue stops and i can resume cruising at say 45 and not feel this hesitation at all.
On the toll road i never feel the hesitation cruising at 2k rpms. A problem that might of lead me to this issue was in the winter below 30 degrees i would drive the truck get to a stop light engine still cold or maybe warming up off the cold mark but when i go to take off from a light its like my fuel pedal doesn't work but the rpms will climb a little then the truck takes off and jerks really hard since i had the engine rev'd up. which made me think throttle sensor immediately or maybe the trans is having issues. since its warm out I don't have that issue now so i believe that it the trans. do you think maybe my hesitation now is also the trans? I never get a CEL. I did recently change the coolant temp sensor and now i am having this hesitation issue.
But I was told the ECM does not care about coolant temp on an auto truck so i dont see how that could affect my performance. Instead the autos monitor oil temp and the manual trucks monitor coolant temp correct? I had an issue like this with the truck years ago when i purchased it i was leaving the gas station on very cold maybe 10 degree day and the truck fell flat on its face and threw a bunch of codes but i let off the throttle and got back in it and it took off like nothing happened. So im not convinced the coolant temp sensor was defective from factory. But this old problem of not accelerating seems to be coming back to haunt me.... and i think its in a new form with the hesitation once in a while. I think i forgot to mention the hesitation isn't all the time!

99 F250LD 4x4 w/5.4 and 215k . I'm sure I'm not the only one with this problem. Just had quite a bit of rain in my area. I didn't drive the truck in it but 3 days after the rain stopped I did. Skipping badly ! It has done it before and will clear itself up after a heat cycle or two. This time it kicked a p0307 code. # 7 cylinder not fire correctly I believe. I got ready to replace the cop but decided to wait a day. In the mean time I pulled the connector and blue compressed air through it and the male connector.
The next morning I decided to drive it before replacing the coil. Absolutely no skipping at all. Drove at different speeds , up heels slow , high speeds, no skipping. Ran the truck for about 20 minutes or so. Is the connector getting moisture in it ? Can I fill the connector with dielectric grease? Is there another problem. I cleared the codes and am going to drive a couple of cycles to see if any come back. Like I said it has done this before but not bad enough to throw a code so I'm not sure if it's always number 7.

I have a 2004 f250 6.8L and recently I've notice the trick not running strong. Is hesitating when i step on the gas pedal. For example, I am driving on the feeder road and fixing to get on the freeway ramp, well i have to spent a bit harder on has pedal to gain speed, but it seems its struggling and I can hear muffler making like a flapping noise. Also when I am going between 40-65mph and I spent on it, the tricks kind of jerks and vibrates. Feels like its coming from transmission. I let go and step on it again and it goes away. What to check??
Miles : 96k
Year: 2004
No Check Engine Light

I took my truck to an alignment shop to have him look over my truck to find a steering wheel jerk and a loud clunk noise. He believes it's in the transfer case driveline. Said to remove the driveline then drive it around and see if it goes away, if it does then that's the problem. So to the question, how to properly take this out? Do I need to make marks with a paint pen anywhere to line things back up or does it matter?
