Golf/GTI VI :: Misfire On Cylinder 4 After APR Install

I had my car tuned over the weekend with apr stage 1. As soon as I went to start the car to leave I started getting a misfire on cylinder 4. We have tried swapping coils around and re-flashing the ecu with no luck.

Details on the car : 2010 GTI 6spd 21,000 miles

Golf IV R32 :: Misfiring On Cylinder 2 And 5

Happened a few times on me lately. While pulling towards the top of 5th, I'll start to see the check engine light briefly blink as if the car wasn't sure, then at the top of 5th, she'll start misfiring on cyl 2 and 5. It's only during the long haul pulls that this occurs. My plugs and coils were all changed about 1k miles ago.

Golf IV R32 :: Won't Idle Right - Cylinder Is Misfiring

The car already has a cel even though I just bought it. Drove home from work this morning had no problems, went to go shopping no problem, come out start my car and it won't idle right, problem. The Cel flashed at me and once driven a tiny bit stayed constant. Seems like a cylinder is misfiring because of the sound it makes and it is hesitant when you give it some gas. What could it be, coil packs (which is what is was in my 24v) MAF, spark plugs?

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?

Golf IV / Jetta IV :: 2004 - CEL Came On - Cylinder 2 Misfiring

CEL came on and the report says #2 cylinder misfiring. Changed plugs, wires and coil. Last step was to change the #2 fuel injector. I changed the 2nd injector from the left but I'm still getting the same message. I was wondering if maybe they aren't numbered that way. It's a 2004 Jetta with Car engine: 2.0L L4 SOHC 8V. Did I change the wrong injector?

Golf IV / Jetta IV :: Again Cylinder Misfiring - Flashing MIL Light?

So a few days ago my engine developed a misfire, flashing MIL light etc...long story short it was cylinder 5's ignition coil. When we scanned it, we picked up a misfire on cylinder 5, and a slight misfire on cylinder 1. Replaced the coil, as well as new spark plugs, cleared the codes, and everything was peachy.

NOW, driving home today.....once again. Misfire, MIL light etc. I'm not a mechanic so I am wondering if it is common for all the coils to go around the same time, or if this is probably just cylinder 1 now going. I'm going to once again get it scanned, but before then...is there anything that could cause ignition coils to just start going bad, other than age.

Golf IV / Jetta IV :: 1.8t - Loss Of Boost After Forge Splitter Installed

Just today I noticed my car boosting to around 1.2bar instead of the usual 1.4bar. The car is boosting to around 1.2 then dropping off to around a bar.

The only thing that I did was install a forge splitter. I presumed that the splitter valve was the issue and promptly put my 007p back on but still had the same issue.

During the process of adjusting the splitter valve I got limp mode several times. I much prefer the 007p and will be keeping that and selling the splitter. What may have happened?

Golf IV / Jetta IV :: Lost Power - New Forge Diverter Valve Installed

So the other day I replaced my N75 valve and upgraded my DV to the Forge 007. For some reason the turbo doesn't spool like it did before, it's lost it's pep.

I've tried the Yellow and Green springs, also I tried them with the shim too. No luck. The car got turbo back exhaust, intake, and stage one program.

Here's the readings I got at idle:

Fuel pressure is KOEO - 0 (That's what it read.); KOER - 30.
MAF - about 70
LT FUEL TRIM 1 - 5.5
ST FUEL TRIM 1 - STAYS NEGATIVE
LT FUEL TRIM 2 - STAYS NEGATIVE
ST FUEL TRIM 2 - STAYS NEGATIVE
ST FUEL TRIM 11 - STAYS NEGATIVE
ST FUEL TRIM 21 - STAYS NEGATIVE
O2 1 - NORMAL FLUCTUATES PROPERLY
O2 S12 - STAYS ABOVE .500
O2 S21 - NORMAL FLUCTUATES PROPERLY
O2 S22 - STAYS ABOVE .500

Touareg :: Put In All New Plugs / Cylinder 5 Is Misfiring

I have a 2008 Touareg 2, V8, 4.2L.

I bought it used (~95k miles) and almost immediately had an issue. #5 is misfiring. Since then, it has been in the shop 10-12 times with no resolution. Here is what I have done so far:

Put in all new plugs/coils sent the ECU to SIA electronics in Chicago for testing - no errors replaced the injector with a new injector on #5swapped #1 for #5 (plugs/coils)checked the harness (dealership said they did this, but not sure if they did or are just tired of me)

Through all this, #5 is still misfiring. The dealership is out of options, suggesting that the ECU is faulty and needs to be replaced ($1600) or they need to swap the #5 injector with #1 to see if that is the issue (~$1000+). Neither of these options sound reasonable because a) the ECU was already tested and b) the injector is brand new, yet the exact problem (#5 misfire) has persisted before and after the injector replacement.

Passat (B6) :: 2006 2.0T - CEL On And Cylinder 3 Misfiring

My dad has 2006 passat 2.0T. In December 2010 he went overseas. During his absence the car was parked in garage and not in use.

So one day I decided to start the car and as soon as I turned it on the car made this noise and check engine light came on. Took the car to a private repair shop and found out the cylinder #3 was misfiring. The tune up for this car was due so I had all four spark plugs changed and the car ran fine for few days. Then couple of days later it started making the same sound and this time around the coil for cylinder #3 was replaced.

A few days after that check engine light came back and this time it was blinking and the engine was struggling to run, took it again to the workshop yesterday and this time another coil not sure which cylinder was replaced. (all this is done at a private workshop). I have a hunch that the car is going to run fine for a day or so and the problem is going to come back

I never had any major issues with it up until now. Bought this car new in 2006 from dealer. I am afraid that this might be a start of a downhill roll from here on I will drive the car tomorrow and see how it reacts.

Dodge - Caravan :: Cylinder 4 And 6 Misfiring

I just had all 6 fuel injectors changed as they were rusted. But the 4 and 6 are still miss firing. I am going through gas more than I should. I had the EGR replaced as it was stuck open. I do not want to pour more big money into this thing. What can I do. Sea foam is not working. Could it be another problem. I am starting not to trust the mechanics.

Volvo :: 1988 240DL - Cylinder 4 Misfiring

My 1988 240DL is miss firing #4 cylinder. I cannot get it to fire. this is what I have done:

Swapped plug wires with the #3 wire. Miss fire does not follow the wire
Swapped plugs with #1 plug. Miss fire does not follow the plug
Tested injector power with a tester and it lights up properly
Replaces #4 injector with a new one, still miss fires.
Replaced cap and rotor
Compression test shows 150 LB in #4
sworn and thrown a few tools, still miss fires.

Spark seems good with the plug out and grounded on the block. What else should I test and or try...

Jaguar - Xj6 :: Misfiring Cylinder 5 / Car Started Shaking With CEL Came On

I used fuel injector cleaner in two different gas tanks; the car started shaking and the check engine light came on. The mechanic changed a sensor but the car was doing the same; I was told that it will take 4 full gas tanks to clean the gas lines. I went to autozone and they told me that the car had a misfire on cylinder 5 and multiple misfire as well. I do not trust the mechanic any more since I had to take the car back to them several times and still is not fixed. They also did a full tune up and the check engine light still on and flashes when I am going about 55 mph.

GTI 337/20th Anniversary :: Stalling And Misfiring In Cylinder 2 And 3

This has been happening intermittently for a while now. The car has about 97k on it and I within the last 1000 miles have replace the timing belt, water pump, coolant temp sensor, tensioners, thermostat, and MAF (OEM BOSCH from ECS).

The car was overheating; all the cooling/timing related stuff was changed, no issues for a few weeks. Then it started misfiring and stalling like a madman in cyls 2 and 3. Ran ran if for the code pulled the MAF and sure enough it looks like the PO never cleaned it as there were probably 2mm of buildup on it; as preventative maintenance I went ahead and just replaced it completely.

Now, less than a week after I replaced the MAF the car will make random little popping noises under hard acceleration, and randomly will just completely stall; without showing the battery or check engine lights, similar to how it was stalling right before the MAF went bad. I live three miles from my office and it has happened going to and from every day for the past two weeks.

As far as I know the car is mostly stock (I purchased in in March). However it does have a knockoff BPV of some sort that I think could be causing the issue as the popping noise sounds like its coming from the passenger side of the car. What this might be (if it's not the BPV).
