Passat (B6) :: Hard Jerk Around 4k Rpm With Heavy Throttle
Aug 27, 2011
I have a 07 20T and today when I went to pass someone on the highway I punched the throttle and the car rev'd up and it started to jerk really hard as if it was not catching the next gear. So I let off the gas and everything went back to normal. Under normal driving the car drives normal and fine, its only when you give it some hard throttle and when it hits high rpm's it jerks, it feels like the car wants to stall. I have 30k miles on it.

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?

When I am driving about 40 in 5th gear and let off the throttle, there is a slight jerk in the engine. Is it a loose motor mount?

I find it hard to smoothly accelerate from a stop with my V6 DSG. I have to be very careful how much pressure I apply to the gas to get a smooth take off...too easy to accelerate to fast or break the tires loose. Can this be reprogrammed?

Bad coil pack after 8k. Was getting a misfire on cyl 1 under heavy throttle so I swapped the coil with cyl 4 and the misfire is on cyl 4 now.

Just recently under heavy throttle my a/c will stop coming through dash and goes to defrost??

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 F-150 Heritage 4.2L V6 Manual 4X4 and over the last few weeks have notice a couple of odd things. First I noted an odd screeching sound, similar to a rock caught in the break drum, but it seemed to be coming from under the cab/bed, not a tire. It only seemed to show up under relatively heavy throttle, which I thought was odd. I went through a car wash with a good under carriage spray, and the sound went away.
A few days later it snowed and the sound returned. I don't know that it's actually related...but that's how the weather went... Now, when I let off the throttle and the engine holds the truck back there is a "thump", and when I reapply the throttle, it thumps again. If I press the clutch in first, then release the throttle there is no thump; so I assume this is something with the drive shaft.
I climbed underneath and found that I do have some play in the shaft, I can twist it a tiny bit so I know that I have play in the shaft which (and I am NO mechanic) I assume is not normal. I can see the shaft turning all the way to where it goes into the back of the transmission so I assume the play is coming from the rear yoke?
I thought I could replace the yoke relatively cheaply but I keep stumbling across posts indicating that with this particular set up, I actually have to replace the whole drive shaft. What I could be looking at, and what my options are?

I just recently bought a 2001 Jetta with the 1.8t (AWD) because it had low mileage and a reasonable price. I've never owned a VW before so I know very little about them in general. This is my second vehicle with a turbo, my first was a Saab 93.
When I purchased the car it had the check engine light on and the codes were Vehicle Speed Sensor and Secondary Air Injection Pump. I was able to get it to stop throwing those codes just by cleaning off the components and reconnecting them. The only predominant problem I've been experiencing is that under hard acceleration in 3rd-5th the car will jump and jerk. Its almost like the car isn't getting enough fuel/air but I'm not entirely sure if that's an accurate diagnosis. I've ruled out transmission issues because there are no problems when driving at a slow-normal acceleration. Any insight on where I should begin to fix this issue would be welcomed because I feel as if my motor mounts will break due the force of the jerking.
My last issue has to do with what happened yesterday. My check engine light came back on randomly when I cranked my car. I had no issues the previous day (besides the aforementioned "jerking) so it seemed odd but what really worried me was when I started driving. Whenever I would release the accelerator the car would slow down suddenly as if I applied the brake. The problem continued throughout the day until I got the codes checked and they read Vehicle Speed Sensor (which I've seen has numerous issues from the factory installation) and the Bank 1 O2 sensor. Today I started my car and the check engine light wasn't on.
My car drove like normal (still the hard acceleration jerking but no dramatic deceleration when I release the accelerator). Now to my question, can an O2 sensor cause a problem like this? Maybe the MAF is bad? Not even sure if this vehicle will throw a code for the MAF ...

I'm experiencing a weird problem with my 09 Santa Fe (just under 15k miles). A few times, while in slow and heavy traffic (and ONLY then) I experience a hard jolt or jerk. The 1st time it happened I thought someone had hit me in the rear but that was quickly ruled out.
I suspect this has something to do to do with the tranny. Though it occurs maybe once or twice monthly, I am beginning to have concerns and suspect that the problem will get worse with time.

The shifting in my Hyundai Sonata 2009 Limited V6 is horrible, having issues with shifting such as a hard jerk from 1st to 2nd when car changes gears driving. It feels like it is pulling back when the car changes into 3rd gear oh and you can forget trying to go uphill. It is completely horrendous it is shifting always up to 3000+ rpms struggling to make it uphill. Any way to achieve a smoother shift and also towards the uphill thing.

2003 Explorer XLT.. All dash lights off finally... had to tape the new ABS connector into the socket on the driver's side. It kept losing signal. Now I am noticing that it is shifting a little hard, definitely not smooth, between 2nd and 3rd. It is not a hard jerk... more like a hesitation. could this be a solenoid? Should I look and feel for additional symptoms? Would it be risky to change out the transmission fluid? or use a cleaning additive?

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.

1997 Chevrolet Silverado 4x4 z71 transmission problems. 5 months ago I had it serviced and A/B shift solenoids changed along with filter and fluid. Now check engine is back on with P1860 code truck also has started shifting more firmly into second and at 65mph it gives a hard jerk.

The other day, my Explorer gave a hard jerk while changing into 2 (maybe 3rd?) gear. Never happened before. I was under 20 MPH & had just stared it. (My speedometer works as do all the dials.) My Check Engine light came on & when I had the code pulled it read quote "P0715."Transmission Speed Sensor circuit condition. Vehicle speed above 15 MPH while transmission output shaft speed below 60 RPM. Possible cause Failed transmission speed sensor or electrical problem"
I got a Transmission Speed Sensor, (which I haven't put in yet), and was told that this would solve the problem. My question is twofold: Is there ANY chance this is a false or misread code and the problem is something else? And could ANOTHER sensor attached to the transmission be the cause? (How many sensors are on the tranny?) All I've read about this problem, say's replacing the Transmission Speed Sensor is preceded by the SPEEDOMETER quitting, but mine works fine.
The truck is a 1997 Explorer 4x4, but I don't use 4x4. In fact I've driven it without the forward drive shaft ever since I had the BW4405 Transfer Case replaced.

I have a 99 350 sd 7.3 low power black smoke sets a p1211 under heavy throttle. Check icp on scanner under heavy throttle falls from 1900s to mid 1700s ipr duty cycle runs about 62% wanting to know if I am looking for a hpop problem or injector issue...

I have a 2005 F-150 5.4L 2WD 90K miles. I started getting a misfire and hard jerk when going uphill. No codes for a few days but misfire got a little worse and more jerking at full throttle acceleration or level throttle up a hill got codes p0300 and p0171. I replaced the fuel filter cleaned MAF and changed plugs Motorcraft plugs (none of them broke during replacement). Miss got worse. Missing at idle and no power 3K rmp to get to 40. Only code pulled was p0171. Replaced upstream O2 sensors and COPs. Will barely idle now. Dies when put in gear. Full throttle barely moves forward a few feet just sputters. Checked vacuum lines cannot find anything. Only code I get is P0171. Fuel injectors next? Or shop?

So for reason irrelevant, at about 500 miles on the odometer, I drove the Prius quite hard the past couple of days. In retrospect, a poor decision as I am now all kinds of concerned as to what kind of damage I may have done. I know break-in is said to be 600 miles so I was below that. I'll describe my 'hard' driving as heavy acceleration, often pedal to the floor, a few hard stops and umm excessive speed (we'll leave that up to interpretation). So I'm just stressing about it now.

I've got an '06 F150 and the steering isn't right with it. It has had a heavy feel and is almost like the power assist is only working half as good as it should. It's been like this for a couple months. I 've had all four ball joints and the steering rack replaced in the last month. It had the heavy steering feel before and after everything was replaced. It also doesn't recover itself on sharp turns, I have to turn the wheel back as I complete the turn. Could it be the power steering pump? I thought it was a mechanical device and it either worked or it didn't, maybe they get weak?

My wife and i have an 07 2.0t and she used to complain that when the car downshifted (on a ramp or something) the car would kind of jerk. At first i just thought she was a woman and didn't know what she was talking about, until we started taking her car into work I noticed the same thing...but not just on a downshift when the car upshifted it would do it as well.....its basically just a quick little jerk like a buck or something..happens maybe 1 or 2 times a week.

Got stuck in the sand pits today. While trying to get out by going forward and back. I always get the front end starts bouncing hard. I always let off. Is this wheel hop or axle wrap?
Whatever it's called. How do I minimize this. It's a shame to have all that power and not be able to lay it down.
