Golf IV / Jetta IV :: While Driving At A Steady Speed Car Jerks For A Moment And Revs Drop
Jul 28, 2014
It is difficult to explain (and google) but my 1.4 16V Golf 4 does this sometimes: while driving at a steady speed car jerks for a moment and revs drop quite much, a moment later it is fine. It feels like I had stepped on the brakes, but when I actually try that the revs won't drop as much. Like my engine seizes up for a fraction of a second but there is no noise. It has done that actually for 3 years, but it was really rare, about twice a year, but now I have had those jerks three days in a row.

Looking for some hint regarding V6 AUE ? Regardless if engine is warm or cold, sometimes happens to me that during driving, while slowing down and pressing on clutch pedal, revs just drop down to 0 and engine shuts down (vehicle still moving). This usually happens while changing gears from 3rd to 2nd on low speeds in city, or while slowing down to full stop in 2nd gear and pressing clutch pedal.
While this happens, I quickly switch off the ignition and start the engine again, which is tricky and potentially dangerous, since vehicle is still moving but my power steering and brakes are not functioning because of stopped engine.
Some relevant info...I have K&N cone air filter intake and ECU is remapped by BTS Racing (German tuning house).
Car is running and pulling normally. In all other regimes of driving, there are no issues or whatsoever.

I've got a 2008 Subaru Outback, manual transmission. When I come to a light, I may put the car in 1st gear with the clutch depressed while I wait to proceed. Then, all by itself, the accelerator revs up to about 2500 rpm for a brief moment. Then it comes down, rests for a second and then does the same thing all over again. The only thing that will make it stop is if I put the stick in neutral and release the clutch. Any way to cure this?

I just picked up my new R (Rising Blue 2 Door w/ S-Roof & Nav) yesterday and love it, except for one thing. When accelerating and changing up through the gears, the revs seem very slow to drop after lifting off the gas and dipping the clutch to select the next gear. It is like there is a delay between me lifting off and the instruction getting to the engine.

I drive 07'es350 and I have felt jerks while driving usually when accelerating or slowing down from speed. Did check with dealer before for transmission after analysis by technician he said it is perfect, recently read on internet and saw fuel filter can be an issue but when called the dealer he said filter is in gas tank and it is lifelong. Not sure what kind of diagnosis I should do to find the issue.

R32 has 29,000 miles. I live at 8000ft. Recently, my R, when traveling back from sea level, starts to have what seems like fueling issues at around 7000ft. These take place by the car being unable to maintain a steady speed and then losing power. Once power falls you can press on accelerator and then will pick up again and accelerate through the gears until you need to back of the accelerator, then the same problem will happen... Once home after lurching around like a kangaroo the car will be fine if switched off and then left for an hour before driving again.

Recently I switched from Revo software with 440cc injectors to Unitronic with Siemens 630cc injectors. After swapping, the car has developed a hesitation issue. It only happens when driving a consistent speed in one gear, for example going 45 in 5th, the car will feel jumpy and hesitate to accelerate with a seeming loss of power. Replaced spark plugs with new ones and the problem still persists. Problem never happened with old software and injectors.

Ok, so I was driving normal highway speeds and all of a sudden, I realize a major drop in power. I pull over and restart it and it changes nothing. Now when I floor it, it takes 20-30 seconds to get to 90K.
I checked the air filter... Nothing. Used a code reader... Nothing. Then I decided to pressure test the cylinders... Nothing, except now the check engine light is on.
The Ol Dub is still drivable, but it is extremely slow and rough at idle. I am thinking it might be a MAF or fuel filter.

I 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.

I still drive the '88 Wrangler I bought in Oct '87. She has 171,000 miles. Recently I had a rebuilt motor,transmission, etc... installed. I had the existing carb rebuilt. This summer, while driving at any speed, the tach would drop to zero and the whole car would lurch. Sometimes so violently my seatbelt would lock up. After a couple miles of lurching it would backfire several times. This is very scary.
Here's the really bizare issue - now that the weather is cold, the issue has substantially (not completely) diminished. On a warm day in the 50's it will act up again. I live in Watkins Glen, NY. Yes, I'm a (Indy Car) racing fan. What can I do?

I had a motor go bad, overheated, replaced it with another motor. Got it all back together and upon test drive I am having a low rpm (below 3k) bad hesitation/misfire. The engine runs just fine at wide open throttle.
First thing i checked for were plug wires and vacuum leaks. The only difference between the old block and the new block is the fact that i replaced the MAF with a new one, as i was getting a maf code on the old engine. I can't get it to throw a code...

I have a 2003 Jetta Gli with a VR6 manual transmission 6 speed. So the other night I am pulling into this store parking lot and all of a sudden my car is just rolling its still in gear and running but when i push on the gas it just revs the motor i thought i was in neutral for a second but I wasn't so I jump out and push it into a parking spot.
Car is running but when i put it into gear and let off the clutch it just revs. so i have i towed to my house it was late so i decided to look in the morning.
So I go out the next day its still the same only now when i let off the clutch it just dies. I'm not an auto mechanic expert by any means any car work i have done is just self taught as needed diving in and figuring it out myself.
I did do the Cv axle on the passenger side last year i bought the one from O' Reilly auto parts. I know its the cheap one and probably a no no. Could this be my cv axle? Did my clutch go out? It moves through all the gears except reverse when the clutch is depressed. Could it be my transmission?

So for the last few days, every now and then when I turn on the car it just revs/accelerates on its own. The rpms will be at about 2k and stay that way whether I'm in neutral or in gear. Then when I go to turn the car off and back on it again it doesn't start. It'll sound like it wants to turn but it doesn't until I let it rest for a few minutes and then it's back to normal.

I have a 94 Ford Crown Victoria with 180,000 miles. I got it from my grandmother in 2008. It's a great car a runs like a dream most of the time. Here's the problem though...for the past three summers, when the temperature outside gets above about 70 degrees, it starts giving me transmission problems. The shifting becomes rough, and it revs and jerks. It does this all summer and then when the weather cools off again it runs beautifully. Do I need a new transmission or is there something less expensive that I can do to fix this? Why does the transmission act up only in warm weather?

Whenever I brake hard the steering wheel jerks to the right and the car follows. And it'll stay to the right until I got about third gear or if I shake the wheel back and forth. Not sure what it is. What could cause this? 01 jetta wolfsburg.....

I am at a complete loss as to what could be wrong with my 2002 VW Gold Cabrio GLX automatic transmission. In the last month the car has been to 3 different mechanics & none of them could solve this problem. The basic scenario: The car starts up fine. The engine will run & everything works fine (AC, radio lights etc).
If I put the car in Drive or reverse...it will idle & move. However, the moment I touch the gas pedal, whether in reverse or Drive, the car jerks & dies. If I put it in park & try to start it up again, the engine will turn over & the car will start, but the moment I touch that gas pedal again, same thing, jerks & dies.
Things that have been replaced so far: ignition coil, fuel pump, the catalytic converter has been removed. spark plugs replaced. Now they are saying that the problem is electrical & are working with the fuzes & wires. The car ran fine for 3+ years & I've had no problem with it.
Yesterday the mechanic called me & said the car was ready for pick-up. I go over there, pay him, I reverse out of the driveway & the minute I press the gas, it jerks & dies. Is this problem really electrical? Or is this third mechanic also grasping at straws?

Cruise control on, set at, say 65mph. I want to lower the speed to 60mph. Tap down... click-click-click-click-click and watch the set speed number drop to 60.... then pop right back up to 65 and the car accelerates back to faster set speed. This has happened more than once now.

I have a 2005 GTI 1.8T with 203K miles, stock except for a MagnaFlow exhaust. My problem arose about a month ago. When I accelerate aggressively and shift from 4th gear to fifth at about 4K RPMs the engine will jump up to 5K RPMs. Happens while shifting from any gear when accelerating hard.
When I push down on the clutch and take my foot off the gas, I get a jump in RPMs. It's kind of like the boost in the turbo is not getting released. I replaced the stock diverter valve with a Forge DV with the splitter. Had no effect on my problem, but now I have that cool sound when I get off the gas.
Could this be the waste gate on the turbo not opening and releasing the boost when I get off the gas? I'm not very familiar with the intricacies of the Turbo functions and the diverter valve.
