Jetta - Volkswagen :: 2011 - Ignition Coil Replaced, Car Misfire
Jul 29, 2014
My wife's 2011 Volkswagen Jetta (2.0 I believe) is misfiring again. We took it to the dealership about 6 months ago and they said that the ignition coil had gone bad. They replace the ignition coil and said that the plugs needed changing as well. I went to Auto Zone and got some decent plugs and changed them myself at home without much problem. It seemed to work with the problem (although it didn't seem to completely fix it) for a while, but it just recently went back to misfiring. The current symptom is that it seems to misfire when the car is warming up, but misfires less when the car is warm.
The dealership says that the plugs that we got were not recommended by the dealer (they recommended Bosch) and that they need to be replaced. I think this is BS and it is not going to fix the problem.

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.

Drove 97 LHS home from work back at the end of June on a 100 plus day, it seemed fine, no indication of any problem. Got in it the next morning to go to work and it would not start. Cranks fine, hear fuel pump. So a few days pass before my husband can look at it. He did get codes. He replaced the ignition coil, put on a new fuel filter, and replaced a couple of modules. It would still not start. We towed it to a service station that we have used for years.
They replaced the camshaft sensor (and fixed the AC). I drove it for 8 days, no problems. Then on the morning of the 9th day, it would not start!! Exact same symptoms. So towed it again back to the service station. Then they said it was the PCM (control module). Husband went to junk yard to get one (much cheaper). Service shop put it in and then said that was not the problem and replaced the crankshaft sensor instead. Say it was ready to pick up. I went and paid again! Got key and came back later with husband to pick it up. IT would not start!!!

Started up my car the other night and my engine light came on, trac light came on... VSC msg came on the dash, engine was rough idling. I drove it home after checking my fluids... i took the OBD scanner to see whats going on, hoping i just need a battery change. Codes popped up P0354, P0300-0306. basically ignition coil malfunction, and my cylinders were misfiring.
I am at 62k miles and warranty crapped out at 50k. the problem was obviously electric, since all 6 were misfiring, otherwise it would only be a few. I haven't had any engine work, I just recently did a proper oil change at home(royal purple 5W30), which I've done since I've had the car in 07.. I took the car to the dealership for the CPU reprogramming for the recall in April.
About to take the car back to get it checked up on and fixed.. I am lowered on coilovers and 20" rims, which gives it a rough ride, but i dont think it would cause this problem. i dont track/race the car and i drive it relatively civilized. Lowered since 30k miles and 20"rims since 50k miles.
What could've gone wrong? timing off etc... i pulled my engine cover to check the connection points for the coils, all seems fine, no corrosion on the grounding points. i was only able to check the front 3 coils, the other 3 were hidden in the back and i wasnt able to look at them. i assume they should be fine as well..

So my check engine light came on a few days ago and I went down to Autozone to check it out with the code reader. The result was "Cylinder 4 Misfire" (the guy said that was as far as the diagnosis would go...) and since I just replaced the spark plugs under 1,000 miles ago, I figured it must be the ignition coil (I replaced coils 1, 7 and 8 about 100 miles ago too).
When I removed the coil, the outside was fully covered in rust, the spring had a tiny bit of rust, and it smelled a little like gasoline. After replacing the coil, the check engine light went off, however the engine still runs rough and doesn't sound much different than before.
What the issue might be? Would a compression test or a better code reader diagnosis give me more insight? I live in Louisiana where we get a decent amount of rain and humidity, so I'm worried there might be a moisture issue down around the spark plug. Also, the exhaust seems hotter than normal and the engine gets pretty hot in a short amount of time.

Recently (5 weeks ago), my 2004 Jetta misfired, which caused the car to shake very noticeably, especially at lower speeds or while idling. The misfire was accompanied by the smell of fuel on the driver side and triggered the check engine light to flash. I took it to the shop (a VW dealer). They ran diagnostics, found it signaled a misfire (but no other major issues/sensors) and told me it was due to the spark plugs/wires. I was dubious, as they were not too old, but I allowed them to replace them anyway, as they assured me this would fix the problem.
Just this week, however, another misfire occurred, also accompanied by the smell of fuel and shaking. This time, the check engine light remained on (constant) for 2 days, and on the third day, it was off. I brought it back to the same shop to try to figure out the real cause of the misfire, which obviously was not the previous spark plugs. My city gas mileage has also decreased over the past month - down to about 20-21 mpg from 23-24. What could be causing such a reoccurring misfire without signaling an issue with a sensor or other part?

I started this string over a year ago (see below). My car continues to suffer the same problem. It now has 62,000 miles on it. I finally decided to take it to the dealership seeing as my local mechanic and 2 VW specialists could not figure out what is wrong - 2 new sets of coils, 2 news sets of spark plugs, and several expensive diagnostic tests that reveal nothing later. The dealership also has no clear idea what is wrong with the car and VW itself has not been useful either (rather useless really). No service bulletins have been posted for my car. I have tried several additives (Techron, Sea Foam) but that did not yield any results. The one thing I have noticed is that the misfiring ceases to occur when the gas tank is a little less than half full but begins to occur again as the gas gauge reaches the refill zone. It misfires like crazy when the tank is full. I am thinking of replacing the wiring harness for the fuel injectors but this is yet another best guess as to what might be wrong with the car.
I have a 2006 Jetta with a 5 speed manual transmission and 35,000 miles. The engine randomly misfires causing it to stutter or stammer. The check engine light is on and has been for several weeks. Occasionally the check engine light flashes. I took it to a local mechanic who ran a series of diagnostic tests (no vacuum leaks) and they recommended having all the ignition coils replaced for all 4 cylinders. They also replaced the fuel filter. I did so but the problem soon returned to which they referred me to the dealer. I decided to take it to a VW specialist in town and they replaced the spark plugs for all 4 cylinders. They noticed that some of the plugs were black with a buildup and some were clean.
Codes listed:
P0202 - Injector Circuit Open Cylinder 2
P0300 (2 separate listings) - Multiple Misfire Random
P0302 (2 separate listings) - Multiple Misfire Cylinder 2
P0304 (2 separate listings) - Multiple Misfire Cylinder 4
P0301 (2 separate listings) - Multiple Misfire Cylinder 1
P0201 - Injector Circuit Open Cylinder 1

2 002 Jetta Bad misfire P0301 a bit long. 02 jetta gls with 2.0 AVH engine auto trans. over summer my brother overheated it & blew head gasket & valves. All parts listed are new between aug and now. I repaired engine as follows new head & bolts head gasket timing belt water pump coolant flange on drivers side new fuel rail and injectors car also has new coil pack, new VW plug wires and 1 week ago new iridium plugs my brother didn?t want car, so i bought it from him. Ran great after I rebuilt top end.
Car did 140 on the turnpike & ran great. once or twice while giving moderate to high throttle CEL would flash and I pulled P0300 as a pending code. Problem stopped after 2 days. last week after 4 hrs of idling(don't ask) started misfiring and CEL flashes constantly P0301 The misfire seems worse at idle and low speed. Car will get to highway speed but has bad pickup. This is what I?ve done/checked New iridium plugs Plug wires 4.5 ohms Coil pack is good and producing enough spark at each wire MAF sensor cleaned Cyl 1 compression good all injectors are clicking and when disconnected cause appropriate CEL error code Brought car to VW dealer for diagnosis VAG COM shows multiple misfire on cyl 1 Mechanic confirmed all the steps I took and components tested ok. He tried new coil pack, new plug and wire for cyl 1 and no change.

A couple weeks ago I bought a 2001 VW Jetta with 176,000 miles on it. The car runs well, but for the past four days this has been happening:
Every time I start the car, after it's been off for a couple hours, neither the gas nor the brake pedal work. I can push them down, and I hear the car trying to respond but it doesn't do anything (well, it does move a little, as though it's in neutral). Then, when I turn the car off and then turn it immediately back on, both pedals are back to normal and work perfectly fine again. It's happened every time I start the car for the past few days.

I have a 2011 Jetta 5 spd, was driving today and suddenly I could not shift in 4th, 5th or reverse. This is the first time this as happen, I have never had any issues with the far. I don't know much about transmissions. The clutch seems to be working fine as I can shift with ease from 1st, 2nd, and 3rd.

I have had the car sense it was brand new and sense I have had it I have had this problem. I mostly notice a problem soon after starting the engine up and come to a stop, but is not limited to that all the times. When I come to a stop the car will feel like it is struggling to maintain an idle as I sit at the light or stop sign and it will actually shake the car a bit. I have noticed when it does do this the fan is on and it might be related to having the alternator trying to keep up with power draw.
I have noticed a loss of power when I am driving down the road it will cut out for maybe a half a second and come back. Usually doesn't happen more than once in one trip. I have brought it to the dealership multiple times to try and see if the can hunt down a problem but it keeps coming back with a clean bill of health. So my question is it something that is normal with diesel engines or is it something that I should take a further look at.
And while on the topic of diesel engines, my uncle a mechanic for diesel engines suggested that I spray a small amount of propane into the air intake to burn up sludge to keep the engine relatively clean. Need to get second opinion of that idea before I try it?

We purchased our 2011 Jetta SE Automatic brand new - first people to drive it - and have had virtually no problems up until this summer. The car has stalled on us dozens of times now and been to two different dealerships for service a handful of times and no one knows what the problem is. We found that the car typically stalls when we're slowing down; however, it recently stalled when we were in Park. When it stalls, the steering wheel locks up, the breaks are nearly impossible to push and everything seems to shut down except the radio. We're virtually a sitting duck for other cars.
When this happens, we're able to put the car back in park, turn it off and back on and drive fine for a while. It seems to be happening more frequently but the dealership hasn't been able to replicate the issue - there are no codes left on the computer and they've literally taken the car apart and can't find anything wrong. They've even 'driven' it for 200 miles and still, nothing. Initially we were told it was bad gas, then we were told it was an operating system update. Now they're trying to tell us that it's our driving style but multiple people in my family have driven the car with the same effect - stalling spontaneously while slowing down, stopping or trying to break.
We've also noticed skipping or slipping between gears when we're at higher speeds but I'm not sure if that's related. It almost feels like your foot falls off the accelerator or slips while you're driving but instead you're actually applying constant pressure.

Jetta starts making a noise on the front left side when I turn sharp rights like in parking lots. There is no VW dealer within a 2hr drive. Take it to local auto repair shop. The guy says it's the wheel bearings on the front left. The Jetta makes a different sound originating from the left front than originally still when turning right sharply.
BTW this sound isn't very loud and is not grinding or popping more of a whoopwhooopwhoooop Go home take off tire. One lugbolt twists off with fingers. First bad sign. Rotors on front not pretty but pretty smooth brake pads look brand new. Still really thick no uneven wear.
Do a sharp left u turn to get to auto parts store. Afs/bulb failure pops on. Solid warning light yet all the bulbs are working fine.
Turn car off. Go buy rotors. Ask about light no one knows. Go back out start car. Light is gone.. okay that was weird.
Replace rotors anyway so they are nice and shiny lube up the important parts. Put everything back together.back out of garage stupid bulb light is back on... restart jetta Its off.
Start driving everything sounds fine... parking lot test left turns quiet right turn SAME FREAKING NOISE. It has never made any noise when driving straight or on curvy road just sharp right turns.

Here is my current situation. No cruise, Replaced clock spring because the air bag light was also on. Still no cruise, checked fuses, they are fine, replaced bulb in gauge cluster. Still no light coming on at all, so I can't do the self test. Do you think my steering wheel switches are bad? Is there anything else I can check?

I have a 2002 Camry 2.4L, ECM 89666-06220, ignition coil 90919-02243. One of the coils has gone out. I got a misfire code on P303. I then moved the cylinder 3 coil to cylinder 4, cleared the code and restarted the car. The new code was P304, bad coil. I found a set of low mileage used coils, 90080-19023. The dealer says this number was one of the three options for 2002. But the pin-to-pin ohm values don't match.
The 90080-19023 pin ohms, 1-2= 348, 1-3=667, 1-4= 490, 2-3= 1100, 2-4= 912, 3-4= open. The 90919-02243 pin ohms, 1-2= 390, 1-3= 673, 1-4=940, 2-3= 1154, 2-4=1403, 3-4= open. How to successfully do this substitution and not burned up ECM ?

The problem is there is no spark coming from the ignition coil. There is power going to the ignition coil but no spark. The car turns over but doesn't start.
I have replaced the crankshaft sensor and the Ignition Module. The wire that goes from the ignition module to the Ignition Coil has been replaced with a new wire that goes directly from the module to the coil .
Also the coil has been checked and its operating within parameters.

Understanding all the needed parts when replacing ignition coils on a honda fit 2007. My understanding is it is best to replace all 4 (are there 4 total?) as well as the spark plugs - also 4?What other parts are needed, does this car require spark plug wires?
Basically, Would this be a good time to replace air filters as well? Car has 116K miles.

Found out today that my third ignition coil is bad, it's a Honda civic 03' my question is, do I have to buy a new ignition coil. I had a clerk tell me I could switch the coils and it would run fine? Is this right? could I just switch the ignition coil with another ignition coil? This doesn't sound right. Well If I do buy new one which would be the third ignition coil? is it counted from left to right or right to left? Are there any telltale signs of a bad ignition coil on sight?

Ignition coils on Hyundai Accent (2011) getting stuck in suction? Or looking for engine vacuum pathway explanation?
I previously (~6 months ago) replaced one ignition coil that had a misfire. I currently have a check engine light with "No Codes" on code reader. My engine is rough idling with very weak acceleration. This occurred when trying to accelerate up a hill. I was looking to inspect the coil resistance and noticed the replaced coil has a pretty strong suction holding it in.

I have a 2007 RX 350 2WD. Recently, the check engine light is on, as well we two other lights are on as well: VSC, TRAC OFF.
I went to Lexus and was told that the error code is P0356. I was told that the ignition coil F is problematic and need replaced. I was quoted 1 and 1/2 hours two 2 hours work and need $412 for the repair. Well, I went to auto zone and was told that No 2, 4, 6 ignition coils were on outside so that it would only take about 5 minutes to replace the problematic one with a new one.
I did the replacement indeed by myself after buying a new ignition coil. Initially it was fine and the light went off after a little while. However, after about 10 days, those three lights went back again. I check the ignition coil, it seems fine and I was told that it is very unlikely for a new ignition coil to go bad this quickly.
I was told that I may need to check my spark plug as well. BTW, when I start the car, the car is a little bit shaky.
