Golf IV / Jetta IV :: 2002 - Engine Light Flashing And Car Jerking When Accelerate

2002 Jetta 2.0.... car was jerking when accelerating and check engine light was flashing, severe loss of power and when stopped at lights it would shake and the rpms would drop and go back up... took it in and was told to get the coil pack replaced. One week later new coil pack - check engine light is back on and yesterday same problem (car was idling rough, and severe jerking/flashing check engine light happened again). Took it to autozone to read the code it is giving P0420.... The shop said i might need new plugs and wires, which were replaced with bosch parts one year ago. Any chances these went bad so quickly?

Golf IV / Jetta IV :: 2005 - Weird Sound When Starts Kicking Into Boost?

I'm the proud owner of a 2005 MK4 1.8t gti, and recently it started making a weird sound when it starts kicking in to boost, where it would normally make a whistle sound while the turbo spools up it now makes a sound that reminds me of a supercharged car, it feels like it could be a leak but I don't have an ecl popping up, it does kind of platoes in the powerband, I hope I'm making some sense ..

Golf IV / Jetta IV :: 2002 GTI 1.8T - Unknown Fuse Blowing Constantly When Engine Starts

I have a 2002 GTI 1.8T with the AWP engine and tiptronic. There is a fuse in the picture below that blows as soon as the car is started. It is located next to the brake booster on the firewall. It does not blow when the ignition is turned on, just when the engine actually starts. I'm not throwing a check engine light, pulling a scanner code or noticing any of my electronics not working. I took a 20 AMP fuse out and replaced with another 20.....and have since blown 5 of them trying to diagnose the problem.

Elantra MD (2010-15) :: Jerking Feel With Transmission When Switching Gears

This is the second time I notice a problem with my 2014 elantra base model. The car only has 13000kms and today the car acted with a weird behaviour. This car has a manual 6 speed transmission.

Out of the blue the car jerked like it had a problem with the transmission switching gears which is weird as this is a manual.

The second time this happened the wife was driving and she said that she was in is third gear and she pressed the clutch and the brake at the same time and she felt a small jerking feel in the clutch like it didn't engage.

The problem is that I cant reproduce the problem. The car is still under warranty and I don't want to go to the dealer with a problem that I cant exhibit.

Elantra MD (2010-15) :: Pulsating Vibration When Stopped / Jerking Feel

My car gives off a pulsating vibration when I'm stopped (at a light, or in my driveway, for example). Its as if someone with huge bass is sitting next to me, but I'm alone. Its a weird "jerking" feel where I can feel my seat shake like a mini earthquake.

I've tried researching "rough idle" but don't fully understand it. Rough idle implies a clogged intake, which kind of makes sense I guess. I have something better than "my car kinda vibrates when I'm stopped".

Its a 2012 Elantra Limited, all stock everything, 53981 miles.

Golf IV / Jetta IV :: Hesitation Like Feel Between 2000 - 3000rpm

I am going to be looking into this a little bit tomorrow with an oil change and noisy hub bearing.

Car : 2002 Jetta GLS 1.8t stock 5spd ~165k miles

Symptoms : Light acceleration (day to day), After shifting into 2nd gear, the rpms come down to 2-2500 range, while accelerating it feels like a hesitation for a couple seconds then continues to go without issue.

Moderate acceleration (casual hwy on ramp, stoplight fun), After shifting into 2nd gear, the rpms come down to the 25-2800 range, while accelerating it feels like a hesitation for a couple seconds then continues to go without issue.

Hard acceleration (short hwy on ramp), After shifting into 2nd gear, the rpms come down to the 28-3100 range. I do not feel any symptoms noted above.

The hesitation felt is enough to cause the car to feel like it had a short loss of power. This does give a jerky feel.

My thoughts : I know there were issues with the coils in this model/year. I have verified through the deal that the vin had received the replacements but unsure if they are the actual replacements. My dad thinks it may be turbo related (which is also stock and never pulled apart to my knowledge).

I found that this KO3s turbo should be fully spooled about 2200rpms. It seems to coincide with my lower rpm accel that maybe I am loosing some of the spool and feeling that?

Other Info : Am I way off or is there anything I can check for easily? I am not very knowledgeable in turbos beyond their basic functions. This is also my first turbo car. I have owned the car 2yrs now. It seemed to have always been there but I don't recall noticing it on the initial test drive. The trans has been replaced since noticing this for other reasons but did not correct this.

Golf IV / Jetta IV :: Transmission Didn't Feel Smooth Whenever Shifted

I noticed a month ago that my transmission didn't feel as smooth whenever I shifted. It would come and go, it'd feel smooth and then out of nowhere it wouldn't be smooth again. It feels similar to when you sit inside a car when it's off and you move the shifter from gear to gear (a nonsmooth feeling). So this Monday I decided to empty out a bit of transmission fluid and add some transmission additive. I drove around and it did feel much smoother. However, it does not feel as smooth as it has always felt. The car runs perfect, it just comes down to my personal preference in smoothness.

Ignition - Jetta - Volkswagen - Misfire - Sparkplugs :: 2002 - Misfiring At All Speeds

My 2.0L Jetta had an intermittent misfire, only at idle. I took it in to the shop, and they fixed a vacuum leak and replaced the plugs. The car drove home fine, but the next morning it was misfiring at all speeds. When it got back to the shop, they said that the coil pack was bad. I wonder if they might have done something to cause the pack to fail, since it seemed to be working fine before I took it in. Their explanation was that the coil had become accustomed to sparking at an adjusted (more powerful) setting to account for the vacuum leak, and when it tried to go back to the factory setting, it quit working. Also, all of the stress from running at a higher output wore it out.

Ford F-150 (2004-2008) :: CEL On - Misfiring Enough To Feel Consistent Buck From The Engine

I am having my trouble with my 06 F150 with the 5.4 V8. I purchased the truck back in the spring and shortly after the truck started misfiring. It was throwing P0306 for cylinder 6 misfire and that was the only code thrown. Seeing as it was out of warranty and right at the 100k mark I replaced all the plugs with Motorcraft plugs, and the plugs that came out were Champion, so it had already been done at least once. This didnt solve my problem at all so I started digging deeper. I replaced the coil pack on the number six cylinder thinking it may have gone bad, but this did not fix my problem either. I had somehow overlooked that the number two cylinder had a Masterpro coil pack that was made in Taiwan or somewhere like that, and after using the Motorcraft coilpack I had pulled from number 6 on cylinder two all my problems went away...until recently.

At the beginning of August my truck started the infamous ticking sound that we all know about. I ignored it for a while, but as I was moving off to college the misifre returned while going down the interstate at around 65-70mph. The truck lost pretty much all power and I coasted off the next exit to see what was going on. After making it off the truck was running perfectly, so I poked on home on back roads at slower speeds to be safe. The next day I took it to the Ford dealership to have them run a full diagnostic scan to determine anything that could possibly be wrong. After sitting in the waiting room for three hours as they searched the guy comes in to let me know they have ran every test they could and nothing was showing up, but the lash adjusters (lifters) on the passenger side of the engine needed replaced as that was what was causing the ticking sound.

Well today I start my truck to come to school and it felt slightly different, but once I accelerated all was fine. Once i left school this was another story though. The CEL was on and the truck was misfiring enough to feel a consistant buck from the engine. I pulled the codes and it is now giving me P0307 and P0316 which are misfire in cylinder 7 and misfire upon startup. What could this be knowing all the plugs have recently been changed and the dealer just inspected the entire engine?

Passat (B6) :: 2006 - Car Started Jerking / Misfiring

I've been out of town a bunch and my car has been sitting out at the airport. I picked it up last friday, drove it home. Today on my way to work the car started jerking - like the engine was trying to rev slightly. When I put it in park, and listened, the engine was jerking or misfiring maybe. The exhaust was a bit louder than normal as well and i could hear the stress in it. I also smelt a strange burning smell. I've called and had roadside assistance pick it up and take it to the dealer.

Golf IV / Jetta IV :: 2002 GTI - Loud Whistling Sound On Cold Start

I am having an issue with my 2002 GTI 1.8T. I have tried searching for an answer to this, and found a couple things saying maybe it could be the secondary air pump but wanted to get more opinions before I go shell out money to chase this problem.

When I start up the car in the morning after having it sit overnight, the car does the normal thing where it increases rpm's to about 1100 to warm it up. During this a loud "whistling" noise can be heard. Once the car is warmed up a little bit, the rpm's decline to about 900, and the whistling sound goes away. When this happens though it almost sounds as if a valve or something is closing causing the noise to go away.

Also, I am unsure if this is related to this, sometimes when I am driving, I will be accelerating and the car seems to stop accelerating as strong as it was, boost goes down from around 8 or 9 psi to about 4 and I seem to lose power as if I had let off the gas some. When I put my foot further down the car accelerates harder again and boost goes back up.

I have already changed spark plugs, cleaned MAF sensor, and run the 3m 3 part engine cleaning kit through it.

Golf IV / Jetta IV :: Won't Start - Misfiring - CEL Came On?

So leading up to today ive had some bucking under load which felt like misfiring to me. I borrowed my friends VCDS cable, checked MAF, checked o2 sensors, checked cat. They are all good. This problem is constant but i did get a misfire code once (random, cyl 1, 2, and 3). I cleared the code and they never came back.

Today as im driving home from work, the bucking problem was much worse. Then the CEL came on. I just checked the code, and it was system too lean. I cleared the code and now the car will not start. It cranks, shows rpm on VCDS and sputters but doesnt even come close to starting.

Golf IV / Jetta IV :: CEL Flashing Saying Cylinder One Is Misfiring

I have a 2001 golf with a 2.0 AVH engine. I recently replaced the coil-pack and was very pleased that the engine was running better, the only problem was the mpg was still kinda low in the 24-5 range when it used to be 29.

I tried to do a compression test but I didn't prepare properly, I thought you left the coil pack plugged in and the fuel fuse. Now I have a CEL that *was* flashing saying cylinder one is misfiring though it has stopped flashing. I drove it 13 miles home and it did improve but its still running rough. Very reminiscent of when my bad coil pack was still in there, a real lack of power.

So I have to ask, what can I do from here? Have I damaged my coil pack or cylinders? Will this likely go away on its own? Is there anything I should do?
