Sonata I45 (YF - 2011+) :: Transmission Will Jerk / Buck Fairly Hard When Put Into Drive
I have a 2011 Hyundai Sonata limited with 68,000 miles on it. Once the car has been warmed up for awhile and I shift into drive after a stop, the transmission will jerk/buck fairly hard. It only does it while being put into drive and I haven't had any other issues while driving.

New here. I have a 2001 F150 which i love but lately has been an issue. I started it up a few weeks ago after it set over night. i threw it in to reverse and notice it hesitating while reversing and it has small trouble accelerating but does buck and jerk while trying to maintain speed. So I took it to my well trusted mechanic and he ran compression test and ran the highly prolific OTC scanner on it and nothing. I have changed my mass flow sensor and I dont show any misfires or any codes pending. I did replace a busted catalytic convertor a couple months back. Im running out of places to turn.

My fuel pump is about 5psi low. Is that enough to justify replacing it. The car likes to buck when accelerating. Had the cat converter tested. It was in good shape. Replace plugs and wires a while back. Regular maintenance. 2002 Monte Carlo SS 100k miles.
View 4 RepliesFord - Taurus :: 2008 - Slight Shudder / Jerk When Put In Reverse Out Of Park
About three weeks ago I noticed a slight shudder in my 2008 Ford Taurus with app. 75,000 miles (automatic). It did not come from the steering wheel, but the car itself seemed to be shaking, but only slightly. Like someone who's had too much caffeine holding out an unsteady hand kind of shudder. It was going in for an oil change anyway, so I had my mechanic check it out, even thought the shudder was gone the next day. It came back, for a few moments while the mechanic was driving. He couldn't tell what was causing it, but said not to worry.
Two days later when I was in the car for the first time that day the car jerked when I put it in reverse out of park. I checked the transmission fluid, and, sure enough, it was about a quart low. All symptoms went away. I took it back in to double check that there was no leak and that everything seemed in good working order. The car was given the all-clear.
Then this week the shudder returned, again, only sometimes. It doesn't seem related to temperature, distance driven, or weather. And the maddening thing is that it only does it sometimes. I checked the transmission fluid again and it is still in the safe zone.
Two days ago, after being parked overnight, the car shook very noticeably for about ten seconds the first time I switched it out of park, first into reverse, then into drive. This was different to the other shudder (I know, seriously). This was a shake, like the bass in a super strong stereo was cranked. Then it stopped and the car drove just fine. I parked it for twelve hours then switched the gears again. Nothing out of the ordinary happened.
Today it had no issue when I first switched gears, but while I drove (for about a half an hour) that original slight shudder was there. This time at all speeds, not just low ones. I went where I needed to go, drove it again about four hours later and it was fine. No shudder, nothing and this drive went through road work with stop and go traffic as well as some time on a highway at speeds up to 55mph. I drove it another time after that, and again, no symptoms. Finally, I drove to the store. The shudder had returned. I parked, shopped for about 15-20 minutes, returned to the car, and it hesitated to accelerate as I pulled out of the spot. It did not jerk or seem to try to catch up. It simply delayed, but accelerated smoothly.
I parked again and let it rest for about 10 minutes, started it up, and no trouble at all. Even that weird shudder was gone. I think this car is toying with me. I'm taking it back to the mechanic, but the trouble is that it doesn't always have these symptoms. I drove it Thursday on a two hour trip and back again with no issues at all. This might make it difficult for the mechanic to diagnose, but at least it's a guy I trust. There are no warning lights on, no smells (unless they are faint as I don't smell things well), and no strange sounds.
Ford Super Duty (1999-2016) :: Buck Or Chug At Like Quarter Throttle While Accelerating
So running into an issue with boost numbers. Factory gauge reads between 20-30lbs on throttle, but I have a SCT x4 and it only reads 3lbs and at idle it only reads .25-.89 somewhere around that range. Are these numbers accurate?
Also, it has developed a sort of buck or chug at like quarter throttle while accelerating, it's sluggish leaving stop signs etc. and it sounds like the waste gate or blow off it holding on even after I let off of the throttle.
Volvo - V70 :: Transmission - Little Slip / Jerk When Accelerating
I have a 2000 V70 with 103K miles. I bought this car used (that's another story!) only about 6 months ago. I started to notice a little slip when I would hit the gas after being stopped at a stop light or something. Now the "jerking" happens even when I am sitting still. It really only occurs when I am just accelerating. I took it to one mechanic who told me it needed a new transmission and to another who ran the diagnostic and could not find anything wrong with it. Not sure what to think. I guess you could say I don't want to believe mechanic #1!
View 30 RepliesGolf IV / Jetta IV :: 2003 - Jerk When Accelerating / RPMs Would Always Fluctuate
I have a 03 jetta 1.8t and for as long as i can remember my rpms would always fluctuate whenever ever i was idling and then there would be sometimes where i would be accelerating and i would have no power and then all of a sudden it would kick in kinda jerky like. About a week ago tho for some reason my car would just all of a sudden die when i would come to a complete stop and it did it about 5 times that day but when it died it would start right back up fine. I've been having this problem for quit awhile.
I have gotten told maybe coilpacks, n75 valve, o2 sensor, MAF i ended up buying a can of sensor cleaner and cleaned out sensor but that doesn't look like it did the trick. i have also noticed when i drive her pretty hard sometimes the rpms will fluctuate a lot more frequently than normal there also times where when ever i start in 1st gear it doesn't feel like i have all the power have than usual and I've noticed it only feel like that in 1st and second gear sometimes.
Santa FE SM (2001-06) :: 2003 - While Driving Buck And Stalls
My wife and I own an 2003 2.7L Santa Fe 2WD with ~176K miles, for the past couple months we have been having several problems with this car, the biggest problem being that it will buck and jump while driving, and is now beginning to stall out. The stalling issue happens while driving at low speeds, while stopped in traffic, or while idling. The engine will rev slightly higher then stall out but will usually start right up afterwards. Only once that I know of, my wife has told me that it would not start right away.
I have read that the cause could be the CPS or fuel pressure regulator. Is there anyway, other than just swapping parts, to narrow down the culprit to the correct fix? The other problem we are having is the hard start after fueling up. I tested the Purge Valve by blowing into the hose, and determined it to be bad and will replacing it soon.
A little history on the car: I replaced the fuel pump and strainer last year, and a couple years we had 2 of the 3 catalytic converters fall apart and clogged the exhaust, so I knocked them out and have been driving with only one intact converter (rear exhaust manifold) since then. I know that isn't good for the O2 sensors, but we cannot afford to replace them at $300+ a piece.
Impala - Chevrolet :: 2011- While Accelerating From A Stop Stutter Then Jerk Forward?
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.
Toyota - Corolla :: 2000 - Slight Jerk Most Of The Time When Accelerating From A Stop
I have a 2000 Corolla CE I bought recently that had 45K miles on it (it has a 4spd auto with O/D).
When accelerating from a stop, I usually take it very slow and I notice that there is a slight jerk most of the time.....it's sort of like I can feel the gears engage. This doesn't happen all the time and it doesn't seem to happen if I accelerate fast.
I did a transmission drain & fill with Royal Purple MaxATF (the drain & fill was only once).
1) Is this normal for this transmission? Also, is there a "pan drop" for this transmission? The mechanic only removed the drain bolt...he did not do the pan drop.
2) During my work commute, I'm in a lot of rush hour traffic where it moves for short distances at 5-10mph. It will shift from 1st to 2nd a lot of times...is better to just put the car in 1st (L) gear? My mechanic said no because it will heat up the transmission faster.
Ford F-150 - 1997-2003 :: Trans Shift Into 2nd With Heavy Jerk When Accelerating From A Stop
2003 F150 XLT 7700 4x4 5.4 Triton. While accelerating normally from a stop the transmission? shifts into 2nd with a heavy jerk. All other gears normal. It doesn't do this under hard acceleration or under very gentle and slow throttle application. Is this a COP issue, a transmission issue or just a driving style thing?

I have recently noticed that if I am driving at speeds above 40 mph and apply the brakes, the car (including the steering wheel) seems to buck/shake. I've learned to ease off the gas and let the speed drop before applying the brakes-- this seems to work, but I'm concerned about what is going on. This is an '07 Nissan Versa...

My 2002 Ford Taurus SES 3.0L 4v 6-cyl is sort of lurching, especially when I'm accelerating around 30-35 mph and my rpms are at 1000-1500. My mechanic just replaced a cracked coil pack, which seemed to work a little but has not eliminated the problem. The engine is also surging when I'm parked with my foot on the brake. What might be going on?

View 1 RepliesFord - Taurus :: 1995 - Grinding Sound When Accelerating
The night before last night on my way home the car made a chemical smell. Ford taurus 1995. So I checked the fluids in the morning and it was super low on antifreeze so I bought some and filled it. I checked several times and it still holding. Then when I was driving it last night it started making a chemical smell again and when I stopped it was smoking a little from under the serpentine belt, which is new. I started driving it this am after made sure the antifreeze was ok but it is making a grinding noise on acceleration. Should I try to make it to work or take it to the mechanic, who is closed on Sunday or call a tow truck? The ac which is normally good seemed to be not working so I thought it might be related to that so I didn't use it this am.

I recently started having problems with my 98 GMC Sierra c1500. I'll be driving and all the sudden it will jerk as if it's shifted from 5th to 1st gear, but the revs don't go up, they drop to about 600 like it is about to die and then it go back to normal revs. It only does this while I'm on the gas and very rarely at idle. I don't know if it could be the transmission or something is blocking fuel from the engine.
View 5 RepliesElantra XD (2001-06) :: Frequently Jerk Or Stutter While Driving
I just bought a 2001 elantra. The car frequently will jerk or stutter while driving like the gas is bad or it is starved for something. When the stutter problem happens while driving the check engine light flashes but does not stay on. It usually only stutter 1 time but has as much as 3. The other day when I was in a drive thru waiting to order the car kinda sputtered during an idle then shut off the check engine light did not flash at this time. It restarted fine after that.
I pulled the codes and read them and I have 2. I am not sure if they are related to this problem. They were U0D00 and P0705. For the P0705 I cleaned the terminal but did not pull the negative on the battery the reset the computer. I reset the codes and the problem still is happening but no new codes are present. The code P0705 has not returned since.
