Accent LC (2000-05) :: 2002 - Hesitation Under Hard Acceleration On Lower RPM
Oct 15, 2012
I have a 2002 Hyundai Accent with a 1.5L SOHC and manual transmission, with 207,000 trouble-free miles on it.
I have recently noticed a hesitation under acceleration. It happens most frequently under hard acceleration under lower RPM, if I'm close to lugging the engine. The engine "hiccups," almost like it is missing a cylinder. It will hiccup 2-3 times until engine RPM's increase, then smooths out.
What the cause may be? Last changes: Plugs at 175K; Plug wires @ 160K, Fuel filter @ 100K, Timing belts at 60K, 120K, 182k. K&N air filter cleaned at 50K intervals, last time @ 200K.

I have a 2005 Hyundai Accent with the 1.6L in-line 4 cylinder engine w/ 160K miles. Over the last few months, I have noticed that when I run the A/C, the car has been at idle for a while, like at a stop light or in park at idle, and I have been driving the car for awhile in the afternoon (summer here), the engine sputters and hesitates on acceleration. The engine makes a pinging, sounds as if it's misfiring and then bolts like lightening, especially when I turn the A/C off. The mpg has declined. I barely get 21 mpg. The car does not have an inline fuel filter, only the "sock" in the tank. I have changed the spark plugs, plugs wires and have run two cans of Sea Foam FI cleaner through the fuel system and the problem still persists.
I am clueless to what could be causing this other than my injectors are still dirty and need a heavy duty cleaning. Could it be an alternator problem because I have noticed the dash lights and headlights get brighter. Could the ignition coil be going out. The car idles fine and the problem disappears when I shut the A/C off and only seems to do this when the weather is hot!

I have a 2002 accent 1.6.(272,000 miles) It has been having this issue for awhile now. It is very slow to accelerate, seems like it is losing power. Also if I press the gas pedal hard it does not want to shift correctly unless i back off the gas pedal some and then it will shift fine. I have had the transmission checked and it has no issues (transmission has be replaced with only about 80,000 miles on it). Also if i try to run the AC it really looses power. It currently does not have any diag codes when I have it scanned. So far I have replaced spark plugs, ignition coil, fuel filter, and a diode that I was getting a code for. I am just curious if there is something that could be causing the issue that will not report a code.

The Accent has been working great recently until the other day when I got in to go to work and now it suddenly shifts very hard into 2nd. And sometimes 3rd.
This problem seems to come and go. Sometimes it will shift smoothly. Other times it will have to reach super high rpm and I will have to let off the gas and slowly accelerate to get it to shift. This seems to happen throughout all the gears and it does not make any difference if overdrive is turned on or off. Also reverse works just fine.
I checked the fluid and it is at the proper level. It does seem to be a little dirty (not burnt) so I am planning on changing the transmission fluid, but something tells me that is not going to solve this issue. It seems like an electrical issue to me. What it could be?
There are no codes at all on the car. Don't know if it matters but the car just turned over to 100k miles. I've been reading on here about all the problems the automatic trannys have in this car but 100k seems a bit early to have any serious transmission problems.

I have a 2010 Sonata GLS 4-cylinder approximately 124K miles which has been hesitating on hard accelerations for about 8 months. It will usually do this when getting on an on-ramp for the freeway or if I need to do a U-turn and get up to speed quickly. What happens is I punch the gas and the vehicle acts as if it's not getting any gas and hesitates or stalls and then it finally takes off. Usually I see a cloud of grey/white smoke behind the car enough that I am unable to see any cars in my rear view mirror.
I do not seem to see a difference when the vehicle is warm/cold. I do not have a CEL nor have had one. I have replaced the MAP sensor, PCV valve and spark plugs (properly gapped). I have done a compression test and am getting roughly 180-185 psi per cylinder. I am not experiencing any oil loss/coolant loss, do not see any oil in the coolant or gummed-up or oily spark plugs. I have also replaced the transmission fluid, doing a drain and flushing the torque converter. I have also cleaned the throttle body, and am using a new air filter and the oil has been changed within the past 1000 miles.

My 2011 stick shift no air Accent has a hesitation or stumble on light acceleration that comes and goes. It may not occur for weeks then re-occurs. It is hard to reproduce intentionally. It never occurs in cruise. The CEL is not on. Most often occurs at 1400 to 1500 rpm with slight acceleration or a slight increase in load as coming to a slight hill. I tried injector cleaner a few times and changed air filter. It seemed more reloaded to induction airflow so I changed the MAP sensor. I understand the 2011 Accent does not have a MAF sensor. It is still occurring. It is fine in steady cruise as well as in hard acceleration. I am wondering if it is a TPS sensor problem. It has 60,000 miles and otherwise runs fine.

The problem started with a slight hesitation around 2500 under hard acceleration. Then it became more pronounced from 2 to 3.5k. The CEL would blink when it happened for more than a few seconds. Eventually the CEL stayed on. Now the car idles roughly with a periodic thump feeling, and any time a load is put on the engine, it feels very rough. I don't have VAG-COM, so I don't have any codes.

I have a 2002 Camry xle v4. It has a hesitation at low acceleration. I've replaced EVERYTHING: Mass Flow Sensor, 2 O2 sensors, plugs, etc. This past weekend I changed the plugs again with a better quality than before and the hesitation went away....for 2 days! Now its back.

(2000 F-350, 7.3L, 205k miles) Over this weekend, I noticed while driving mostly in the lower gears, that there was a slight hesitation with the throttle pedal depressed about half way or less. Seem to get worse as the day went by, but no lights or anything came on. Changed the fuel filter and added a fuel injection cleaner to the tank. Checked the oil and it was low, so I filled it to the correct amount.
Drove it around the next day, and it seemed to be good, until it warmed up some, and continued to hesitate. The hesitation seems as if it's not getting constant fuel, and the truck jerks a little. Once you get up to over 2000 rpms, it goes away. Looking up other reviews on similar issues, most have pointed to the throttle pedal sensor and just changed out the pedal assembly. Before I take it that far, I wanted to see what was the corrective action.

Lately I have been having some trouble with 2002 Oldsmobile Alero v6. When the car is sitting in park I have noticed that the engine idles roughly, And when I try to drive it, the car hesitates on the acceleration every now and then. Also the emissions light (the orange one) will come on for awhile and then dissapear. At first I though it was dirty fuel injectors so I added some Fuel injector cleaner, but that has not fixed the problem. I was thinking the park plugs may need replacing?

I have a 2005 Accent Manual, and my check engine light came on a little while ago. So far since then, my car has started to hesitate, and sputter at times. It just doesn't run like it used to. I have owned this car for four years, and it now has 117000 miles on it. I went in to one of the automotive stores in my area, and after telling the gentleman that works there about my car, he sold me some spark plugs, and spark plug wires, because I have never replaced them for as long as I have owned the vehicle. I did and it still sputters and what not. So I went back in and they hooked up their machine to my car and printed off these codes:
P2401
P2419
P2405
P0036

I have a 2000 Tahoe with the 5.3L V-8, 351,000 (yes that is correct) miles. Runs great except it has recently developed a stutter, hesitation, skip, I don't really know how to describe it, under acceleration or at steady speed. This is an intermittent problem and it is driving me batty. The only codes are a P0420, maybe after 350k miles it needs replaced? Would that possibly cause this issue, or am I looking at something more sinister?

Our intrepid 3.5L with 135000 miles has been acting up a bit. Its had a couple hard shifts over the last few days/week that almost seemed like an engine hesitation, and this morning when slowing down from highway speed into a small town, it abruptly shifted down to 2nd and stayed there like its in "limp mode" ??.
Pulled over and checked fluid. Level looked good and smelled ok but has a brown tinge to the pink fluid.
Started to go again and it still wouldn't shift. Pulled over and shut car off. Checked codes P700 and P138.
Started car up and it shifted fine for the next 28 miles. Shut car off and parked it.

I have a Honda Accord EX 4 cyl. 2002. It has sluggish acceleration and hesitation problems. I put in new plugs and that improved it some. My mechanic says I should pay him to clean the fuel injectors. What will work best? What needs to be cleaned? Would new plug wires work? Gumout? Big differences in cost.

The problem starts after about 5-10 mins of start up and normal driving. First signs usually come leaving a stop light or stop sign. Hesitation, jerkiness, rough acceleration. It's usually slight, just enough to feel it. Soon it really shows up while keeping the truck at a steady speed, say 40 for example.
I finally heard what I would describe as a puffing air sound and figured vacuum leak.. finally! Nope.. it's coming from the rear underneath of the vehicle. I can't hear it in the engine, or the tail pipe.
2002 Ford Explorer xls 4.0 125k miles, I've replaced the air filter, egr valve, pcv valve, cleaned the maf and covered about every hose I can reach with carb cleaner checking for a vacuum leak. I've yet to try some of the other things due to hearing that puffing sound.

I have a camry 2000 automatic transmission with 150 K on it. For last few months I am having this sporadic issue with it having difficulty to change the gear from lower to higher gear(from the first to second, i guess). It goes like this, when i start speeding up the car, its having difficulty to move to higher gear, it just revs up to like 5 - 6 K rpm and with a jerk it shifts the gear. And at the same time check engine light goes on. And during the time this check engine light is on, it does this same thing a couple of times or so.
Then after some time the check engine light goes away and the car runs just fine without any issues for some tine and then the same thing happens again and after some time the issue and the check engine light goes away and the car runs just fine again. this keeps happening every few weeks. So I took the car to the mechanic (check engine light has gone away at this time, who told the code was showing some "speed sensor" issue and they replaced this. After that the car ran just fine for a couple of months. But its starting to do the same thing again.

My problems started out around the beginning of the year. Mostly, it was the transmission. It would slam really hard when shifting. Worst, sometimes while on the freeway, it would shift on it's own, for no reason, into a lower gear and get stuck. (Happened twice and was really scary).
Along with this, a couple times I would start it up and it would rev really hard, about twice what it normally would.
Usually, with the revving, I could turn it off and back on, and it would stop. A few times I could disconnect the battery, reconnect, and it'd be fine.
As for the tranny, I could turn it off then back on and sometimes that would work. Other times after a few miles it'd work itself out.
I did take it to my local Hyundai dealership. The first few times they couldn't get any code to pop, and they couldn't simulate the issue. It was very random when it'd happen. Luckily, on the 3rd try, they did get the tranny to shift hard. They said it was a bad tranny and replaced it (free due to warranty).
Unfortunately, that hasn't gotten rid of the issue. After a few months... maybe 3K - 4K miles the issue is back. Again, it's very random.
I've had the high revving which I've had to disconnect the battery to resolve. And the tranny is slamming again.
I don't notice any other issues. No engine light (except the one time the engine was revving really high and I had to disconnect the battery to reset, then the light went off).
Sometimes I can go a month with no issues. Sometimes it'll happen back to back days.
Could it be a computer issues? Is that something I can fix/change out as a novice?

I have a 2000 accent. Automatic tranny with 167000 miles. My current problem is the car is misfiring upon acceleration and engine revving. I have to accelerate very slowly to minimize this but i once the engine revs up enough I can give it more gas and it will rev normally with plenty of power. I have had to unplug the maf to keep it driveable. Ive never had a car stay running after disconnecting the maf so this is strange to me. My accent barely stays running with the maf connected. I just got the car from my dad and he had it fixed and it ran good for awhile with the maf connected so I don't think it is the maf. But the same problem came about and we had to disconnect the maf again. And he cant remember or is not sure what was exactly fixed on the car. I've read up about the purge control valve and havent had a chance to check it out but some of the symptoms fit.

I've got a 2000 accent 1.5, and I keep getting a code for a cylinder 3 misfire, when I change the spark plugs, it runs great for about 50 miles or so, then back to square one again. I just changed the coil pack the other day and there doesn't seem to be much of a difference. It has massive hesitation under heavy throttle, and the check engine light begins to blink if it sits and idles for too long. I've scanned it multiple times and it's always been cylinder 3, so it's definitely set on that one... I'm about stumped on what this could be. Also, the previous owner said that after a hot day of driving, the ECU fuse under the hood will blow out, what could cause either one of these things?

I have an 01 accent with a 1.5 engine. Coming up with codes P1123 and p1128. I sprayed manifold with brakekleen and didn't get. Any change in Rpms. Also sprayed maf sensor with maf cleaner. And still have same problems. Some hesitation when I start to go. And while I'm driving. My gas mpg is 25 mpg which seems way low. I just bought car and next day engine light came on with above Codes.

2002 accent 1.6 motor and 5 speed,when I take off the motor sputters for a moment then is fine and if I let it slow down in any gear and step down on it it will sputter again then is fine, so far I have changed the plugs and air filter cleaned the throttle body and MAP, the wires and timing belt were changed out not long ago, took it in and hooked the machine to it and it said misfire bank 1 oxygen sensor upstream so replaced it and still have the problem, the body has 200,000 on it and the motor 100,000.
