I am the original owner of a 2002 Camry V6. Recently when you take the foot off the gas to coast or just maintain speed there is a sensation of jerking- it disappears as soon as you accelerate. Took it to Toyota dealership- they were clueless- they wanted to change the transmission fluid.
View 1 RepliesI have a 1998 Toyota Camry v6 with about 90k miles on it. When I am driving and hold the gas pedal steady the car jerks and hesitates. If I press down on the gas I can power through the problem. It also does this when I set the cruise control. There is no check engine light on.

It has a weird issue.
In the early morning, from my house to work around 7am, I have to drive around 20 mins on freeway , I exit and drive for another 5 mins on local street which is up and downhill, at red light or when I have to turn, the car begins to hesitate like hiccup and stall on me. The car cannot start again immediately, all power is still working, the car is trying its best to turn over but it fails. However after I wait couple mins, I can restart the car. Then, the car will run just fine, absolutely fine the rest of the day.
The weird thing here is, on days I don't have to work, I start to drive it at around 10am when it's warmer and there's sunshine, and not up and downhill, it never hesitates or stalls. Even I try to drive it up a big hill near my house at noon, nothing happens. So I'm not sure if driving up and downhill playing a part in this problem.
It doesn't happen all the time when I have to drive to work in early morning, up and downhill, but more than often. The car drives great on freeway, idle excellent around 500-600 RPM. One more detail, the gas pedal kind of vibrates (very small vibration) around 1600 RPM, and it's annoying. I'm not sure if it is relating to the issue.
Here what I did to the car:
1. Clean throttle body.
2. Clean Mass Airflow Sensor. Didn't work. Then I replaced it with a used OEM one.
3. Put Techron Additive in the gas tank.
4. Replace Air Filter.
None of the above works, but I think somehow it improves a tiny little bit.
1997 licoln continental, automatic. Around first and second gear, the car hesitates to pull and will 'jerk'. While it's doing this the car can be revved unsynchronized as it will try to 'jerk' it's way past around 1st and 2nd gear. Eventually, it smooths out after it's into 3rd gear and drives normally though after roughly getting through 1st and 2nd.
In 1st and 2nd gear, if the gas is let off for a bit before smoothing out.. it will often sometimes completely come out of gear, not pulling from any power given. If it does, after popping out of gear the car will not go back into gear, even from a complete stop from 'park' then trying to put it back into 'drive'..no response to power given. However, it goes back into gear just fine, roughly again, if you turn the car completely off and put it back into 'drive'. Obviously, the car also will hesitate even worse on an incline from a dead stop.
Another note, there is a slight wobble to the crankshaft pulley.. though, i feel this issue is completely unrelated to a harmonic balancer noting that the car just pops out of gear and goes back in gear just fine when it is turned back off then back on.....but, not unless the car is completely turned off?What would the obvious culprit be...? Torque converter?
I changed all of the brakes on her car yesterday, test drove it, everything was great. Put close to 100 miles on it w/ no issues. Therefore, I don't think it's anything I did.on her way to work, the CEL came on. The car has a rough-ish idle, and jerks slightly in low RPM. I went to Pep Boys and got it read. it threw 8 codes:
P0171
P1130
P0300
P0301
P0303
P0305
P0442
From what i've read, the p0171 is the system is running too lean and p0442 is a leak somewhere. The 300s are cyl misfires.I don't want to go replacing every conceivable part. What these codes mean in conjunction?
Background Info: 2002 Camry LE w/ 2.4L engine with approx 90,100 miles. Battery is approx 3 years old and is fully charged (used a trickle charger)
Yesterday I noticed the car was hesitant when I was starting the car. Every time I started the car it took longer to get the car started. Then today, I tried to start my car but all i got was a sound that sounded like something was spinning. There was no clicking, no sounds of the car trying to turn over. So I attached the charger to my car and it said it was good (plus the lights worked, the radio worked, windows rolled up and down).
So I used my breaker bar and hit the starter twice, went back in to the car and it started up, very hesitantly. Now my car will only start when i hit the starter first, otherwise it makes that spinning noise.

MY 2011 Sonata has 84K miles. Last couple of months, I've noticed it engine jerks / hesitates / stalls when going from 40 mph to 60 mph. Once it reaches 60 mph I can go 70mph or higher without any problem. I've made several visits to dealership without any success. First, they diagnosed as bad oxygen sensor and bad spark plugs. The problem did not go away after replacing both. According to them it does not give any error code. Now they're asking to perform fuel cleaning service. I feel they're shooting in the dark. Does it sounds like problem with the automatic transmission i.e problem shifting into higher gear.
View 18 RepliesWhen I'm driving at Highway speeds, if I let go of the accelerator to coast and then reapply the accelerator, I get a jerking, bucking sensation. It's only at high speeds over 60 mph or so. I'm only coasting for a second or two, not long at all. Otherwise the transmission works well.
View 8 RepliesPurchased this car new. 2008 GLS w/ V6 2.7L engine. Wife's car, so I rarely drive it. She's complained for a month about an intermittent issue with the jar "jerking", usually during slow speeds.
I felt it for the first time myself. Was halfway through a pretty tight curve at around 20 MPH, starting to slowly accelerate when I felt a definitive lurch. might have been momentary loss of acceleration, or transmission. Not sure which. No CEL thrown.
I did see another thread mentioning a 2007 with a similar issue, but that person had codes thrown that pointed to a Throttle position sensor and a need to reflash a transmission. Think I'm seeing the same situation, or would this be different ? Absent any CEL, I'm sure the dealer will not be able to find it....
2002mazda protege5,2.3 ltr engine.had the timing belt changed, then the problem started after the belt was replaced.took back- scan showed short in #2 cylinder and vacuum code.they fixed coil problem for #2 cylinder but vacuum code went away.once rmp get above 2500 accelerates o.k.hesitates when taking off from stop sign, etc.could vac hose be missing somewhere?seems to act like it floods when taking off.does vacuum control timing advance or gas/air mixture?
View 5 RepliesI was just wondering if this is normal. On flat road I can coast without touching the gas pedal and go 15mph. Is the idle set up too high?
View 5 RepliesI was wondering what could be causing my Elantra to hesitate? I have the 2.0 5 speed 4 door sedan. It only hesitates below 1500 rpms in all of the gears. I was curious if plugs and wires could work out pretty good? I know when I changed them out in my old Saturn SL1, that stopped the hesitation.
View 7 RepliesMy 2002 Grand Prix jerks when shifting. It originally happened earlier in the spring but fixed itself after I had a coolant leak fixed. Now it's happening again. The coolant and ATF levels look okay. I found one possible fix on Google but wanted to get some other opinions first. What's wrong, or how urgent it is? Is this something I might be able to fix myself without a lot of trouble?
View 7 RepliesRan torque for the first time on my f250, I used it for diagnostics to see if i can find out whats causing the surging. At a red light sitting idle it shows my icp at 705psi seems high to me? I'm running a dp tuner, it was set at stock for this run. It starts surging between 35-50mph and when coasting at about 60mph, surges during light throttle or maintaining throttle at low speeds. If i go about 70mph and up it runs like a champ. Ive changed the tps(entire pedal assembly), uvcg connectors, icp and pigtail. No CEL comes on, torque shows ipr is good, working on hpop pid. I just bought the truck last month and haven't been able to enjoy it much since it started doing this. ...
View 14 RepliesI have a 2002 Toyota Highlander that sort of chokes. At random times while driving, the car hesitates on acceleration, chokes a little, and then continues to accelerate. It is an automatic transmission but it feels like I can feel the shift in gears. usually happens at low speeds (20 mph). no matter time of day or warm up period. I have been having regular maintenance at dealer. there was a caution note that I would need spark plugs replaced... is this it? a result o f needing new spark plugs? or something else?
View 6 RepliesI've noticed that when I'm coasting to a stop and my speed gets to about 27 MPH, the transmission downshifts (RPMs increase) until I reach about 22 MPH. I'm not applying the brakes at the time.
It's a bit annoying as it sometimes bleeds off just enough speed that I need to accelerate to reach the point I was planning to stop at. Is this normal?
Why my 2010 auto trans 4cyl Camry often feels like someone is applying the foot brake when I take my foot off the accelerator? Is it the auto trans downshifting? When I feel it occur and slip it into neutral, it releases and I coast freely again. It's really annoying sometimes especially as I've been driving a 1995 Camry auto for the past 15 years which does not do this.
View 14 RepliesWhat can cause a car to jerk forward while accelerating? Other symptoms include loss of HP and MPG. Recently had spark plugs and wires changed. Regular maintenance. I am about to see my mechanic and ask him to check the fuel pressure.

I have a weird issue with my 2002 4x2 manual Nissan Xterra...when I drive along (usually happens when I'm in 3rd or 4th gear), and depress the clutch pedal to start slowing down for traffic, while the gear lever is still in the 3rd or 4th gear position, the rpms start coming down as the car coasts, but then a strange grinding/whirring/grumbling noise starts happening. The noise immediately goes away if I pull the gear lever into neutral, OR if I re-engage the clutch to start accelerating again. So, it only happens when BOTH the clutch pedal is depressed, AND the gear lever is "in gear". What could this be? The car has about 115K miles, but I believe the previous owner changed the clutch recently (80-90K), and the clutch itself feels fine.
View 3 RepliesI just bought an 05 Camry with 40k miles. Runs great. Decided I'd have a tranny flush and coolant flush done. Oil was done recently. A couple hundred miles later and today I've got a noticeable hesitation when accelerating. It's not a herky jerky stutter, but a smooth, consistent like a loss of power like I'm quickly letting my foot off and back on the accelerator. Doesn't seem to do it when not in gear, just under acceleration. Checked trsnny fluid and it's ok and full.
