My '99 Passat (1.8t) shakes and jerks violently during acceleration. If the terrain is smooth & flat I don't seem to have a problem. The problem gets pretty extreme during acceleration especially if going uphill. Also, it seems as if it really kicks in when the transmission shifts gears. I have replaced the fuel filter, dump valve, & all 5 mounts to include the front snub mount.

View 12 RepliesIn 2007 purchased above referenced vehicle. First week it began to jerk a little when changing gears or just driving it. Last week it began to jerk violently when putting it into gear; then it finally died as i pushed on the brake. It was towed to AAMCO for diagnostics and they finally said the problem was out of their league, or it would cost 800-1000 for complete car diagnostics. Referred me to master mechanic. But I'm taking it back to the dealer. QUESTION: because there seems to be a history of electrical related issues with the model, and recalls found back in 2004, would this car be classified as a "lemon" or is it possible for the electrical issue to be fixed, or should I "junk" the vehicle?
View 1 RepliesE 350 with a 5.8 drive ability headache 94 E 350 with a 5.8. about 1/2 throttle or under quick acceleration it bucks violently and will die if you don't let up on the throttle. This all started when it was run out of fuel. I found the condenser wire was shorted to its own body. Causing the PCM fuse to blow. I have since replaced the condenser. Same problem exists. I have replaced the map sensor with a known good one, same with the O2 sensor.
The TPS is in range and goes through its range smoothly (this was done on my scanner) Also replaced the fuel pump either due to the fuse blowing or running it out of fuel it wasn't working. Fuel pressure is 30 to 32 psi. I've checked the EGR for leaks and proper operation. I have noticed its very hard to start when its cold. Someone has had problems with it in the past as cat is new and i have noticed some things have been removed or replaced recently. The van was just purchased a few weeks ago by my buddy.
I have a 1999 Passat 1.8t manual transmission... My car shakes like it's going to stall and sometimes actually stalls when I come near to a complete stop. The car drives really bad... it jerks when downshifting and on accelerating... The performance of the car is crap. also When i put the car into neutral and coast to a stop, the revs will bounce up and down. I posted a couple months ago about this problem and I was told to clean the throttle body. I then cleaned my throttle body and replaced the gasket. This problem went away for about 5 days and then was back again. This problem is the worse when I go to school, which is when it's about 45 degrees outside.
View 9 RepliesIncosistently when accelerating the car jerks (like when wheels spin out in rain). Car works just fine in Idle and has been working great, except for the occassional jerking. I would like to know what I should check and if its dangerous to drive, depending on what the problem might be.
View 5 RepliesIt just started doing it the only way I can seem to figure out how to explain it is at about 50 to 60 under slight acceleration or uphill it bucks or jerks like you have a trailer jerking. No check engine light this thing is driving me nuts... 2004 f150 5.4 ...
View 14 Replies2003 Honda Odyssey EXL with 236,000 miles on it was jerking, very scary, and the rpms were revving up while driving. We asked around and had it checked and was told it was the transmission. We waited 9 months, not wanting to put the money into it and let it sit, not driving it at all. Then we decided to fix it last week.
We thought we were replacing the transmission, but, after working on it, the place we took it - very reputable - only did the solenoid, saying that fixed the problem. When we took it home an hour away, it was fine - much, much better than when we left it. But, the next day my husband felt a small jerk. We took it back that night and left it with them for a couple more days. They couldn't make the problem recur, so they sent it home with us. We were getting ready to go on a major road trip, so we had the oil changed, and all other stuff for regular maintenance seemed good. Had all fluids checked and new tires on and new battery. Also had recall done on ignition switch. Left on major cross-country trip. Drove about 5 hours and it started again. Just a little - one time. No place was open and we were on deadline, so kept driving cross country.
Eventually the check engine light came on (can't remember if it was before or after started jerking), but that has been on for a couple years and we keep having it checked and they tell us it is not worth fixing - hard to figure out the emissions problem. Could be several things. One was the solenoid, another the gas cap. We had both those replaced. Problem has gotten worse as we have crossed the U.S. on Memorial Day weekend - so no opportunity to have mechanic look at it or get codes due to everything closed. Checked transmission and oil fluid levels, and they are good.
If we accelerate VERY slowly, we are okay. But, the TCS light comes on if we accelerate too quickly sometimes, and it will stay on until we stop and turn the car off. Sometimes it doesn't come on at all, but the check engine light is always on now. In the last 200 miles, we now have occasionally the D (drive) light flash - if the TCS light is on and we are getting jerking, and the rpm's stay up in the high 2's or close to 3 and the van doesn't seem to shift into the higher gear. If it flashes, it won't quit or shift into the higher gear until we stop for maybe 20-30 minutes. Then, the light will stop flashing and the rpms are okay. As long as we accelerate really slowly, really slowly, it won't flash again. One time, on an off-ramp, we jerked when we were decelerating, but that was only once in about 1500 miles - or ever as far as I can remember. The jerk on acceleration has actually been going on for a couple years, but it was always just momentary and only occasionally. Now it is a problem.
2008 GS460. 100K miles
I have noticed when I accelerate on a entrance ramp to the highway I notice the RPM meter jerks a little like it's trying to suck for gas or something else. I can feel it in the car too. This is the only time I have noticed this. I have replaced the spark plugs about 5K miles ago.
I did bring it into the dealership a few months ago to get the fuel pump replaced as I noticed a hissing noise under the drivers side read door. They said fuel pumps rarely go bad on the Lexus. The mechanic did some fuel pressure tests and said everything looks good. He also said noise is the return line back to the pump.
I have an issue with something when I stop. When I apply the brakes and come to a complete stop, right when the forward motion is completely stopped the ex kind of rocks back on the shocks. When that happens the ex jerks just a little. Kind of like if the brakes were sticking to the rotor, or the shocks are sticking. Then when I start to accelerate it jerks again. How can I tell if the brake hoses are bad, calipers are bad, or if it's the caliper slide pins, or if the shocks are bad?
View 11 RepliesI am getting what i think is death wobble at around 45-55 mph in my 2012 but not near as violent as others/videos have described. I do not have a lift but i do have 35x55x12 mud tires. I got an alignment but it is still happening. I have read that it is usually caster but i thought this was only in lifted trucks? I am putting a 3.5 inch lift on it to better clear my tires in a couple of weeks and it comes with a trac bar relocation bracket. Will this fix the issue? I have checked tie rods/ball joints as well and they seem ok. Will the relocation bar fix the issue? I also have dual stabilizers on it. That firm up the steering after i put the tires on but the intermittent wobble is still there. Most of my driving is between 45-55mph so it can become annoying.
View 14 RepliesI have a 2005 F250 with the 6.0L. I went to pass a person, I got the truck up to 80 - 85 mph and made the pass. Everything was fine for a second or two, then the truck started to rock back and forth violently. It shook so hard, it removed cups from the cup holders. I never felt I lost control of the truck, but I have never experienced anything like it before. I slowed the truck down to about 60 mph and the problem stop. What in the world could have caused this?
View 14 RepliesMy 02 f250 started shaking violently until when I accelerated and the mechanic said it was the wiring harness in the computer. He said it was caused because of over revving I think it was just because the harness was old. Is it because of over revving? Will it happen again?
View 7 RepliesJust purchased new to me '08 F-350 w/ 150K miles and I'm currently having this issue. It will steer to the left and right sharply, and it will stop if I park the truck for a couple of minutes. Can't drive it on the road at the moment as it's too dangerous. Doing a search revealed the following: steering box or u-joints. Should I try using penetrating oil on the u-joints and see if the problem goes away? What is the easiest way to gain access to the u-joints?
View 11 RepliesWhen I bought my car (used of course) the guy told me that they had replaced the water pump and the timing belt. When I test drove it everything felt great. turns out that after about ten minutes (cold motor) when the temp gauge reaches midway it starts to stammer on acceleration. this was last friday. yesterday on my way home from work my gas light had come on. I was going up a hill when the CEL lit up. I got gas this morning on my way to work. at one point i had to hammer it a little to get out in front of someone. thats when the once solid CEL began to blink.
View 11 Replies2008 f250 standard cab long bed 2wd base model 5.4. This thing has been great for the last few years i i owned it but it developed a shake since i got new tires. My mechanic mounted 4 new Hercules Terra trac at 2's on my 18 inch wheels (275 70 18) and when i got the truck back it was shaking violently at anything over 45. Mechanic says the new tires are heavy and its affecting other things...sounds plausible. So here i am a month later with a New steering stabilizer, all new ball joints, new shocks, new u joints, and 1 new tire (he said 1 of the brand new Hercules had a broken chord). The shake is 80% gone but this truck is still not the same. Anything after 65mph and it has a feint wobbly bouncy shake. I don't think its the dreaded hop that everyone gets on these. I have 2 theories:
1. These cheap tires just suck and will never be right
2. The cheap junk Monroe shocks he put on are way too soft to do anything
so what do i do? Should i get some crazy shocks or will that make this truck even bouncier? Im worried about making it even stiffer than it already is.
I have a kind of weird noise and feeling when I turn left with my 1999 1.8T Passat. It sounds like "clac clac clac".
It almost only happens when I'm stopped and I'm accelerating to turn left (U-turn or street crossing). I was wondering if it could be the left universal joint? I don't think and am pretty sure it is not the wheel bearings, but tell me if I'm wrong.
I have a 99 VW Passat with 2.8 V6, FWD, Automatic tranny and it currently has 94.5K miles. Under semi hard or hard acceleration from either a rolling or standing start, the car vibrates something terrible. Steering wheel has bad vibration and the whole car shakes. If you back off and accelerate very slowly its pretty smoother.
I have had the tires balanced 3 time but the last 2 times the dealer and Sears didn't even move the weights. When cruising at amy steady speed on the highway there is no vibration whatsoever. So I don't think tire balance is the problem. The dealer then put in two brand new half shafts but its no better. I asked them to check the motor mounts but they said they are fine.
I am having a problem with the vehicle. The other day I noticed that the car jerks a little bit when stopped. I was sitting at a red light and had my foot on the brake. While the brake was applied, I let go of the brake but not enough for the car to roll and then reapplied the brake fully. I did this because I though I got the green light and when I realized it was still red, I reapplied the brake. As soon as the brake went all the way I felt a small jerk on the brake pedal.
I immediately noticed it and thought it was weird. It almost felt like I quickly let go of the brake pedal and quickly applied the brake again. I did it again soon after and felt it again, then again, and then again. I made an appointment at the dealer where the vehicle was bought from to have it looked at. I hope they don't think I am nuts only because you have to do it a certain way in order for it to occur (push the pedal all the way, release the brake the slightest amount, apply the brake and then feel the jerk in the pedal). It definitely doesn't seem normal.
Problem: 55-60+ mph hit a bump front end shakes violently. Slow down to 40 mph it stops. DOES NOT happen every time, and may only happen once a week, but when it does my whole front end feels like it will come loose.
Solutions to date that have not worked:
1. Rotate and balance tires. (tire shop)
2. New shocks. (me)
3. New steering stabilizer. (me)
4. Changed ball joint and bushing in track bar. (Dealership)
5. Check ball bearings and seem to be ok. (me)
6. Check tie rod ends and are ok. (Dealership)
The only other options people have given me:
1. Dual Steering Stabilizer. (Have had truck since Jan and hasn't done it in about 19,000 miles. Why would it need it now? Truck has 109,000 miles on it.)
2. New tires. (If it were the tires wouldn't it do it all the time? )
