GTI 337/20th Anniversary :: 2004 GLI 1.8T - CEL Came On / Code P0303 Cylinder 3 Misfire
So I have a 2004 Jetta gli 1.8turbo and my CEL came on last night from normal driving, after it came on it still drives the same. I had it scanned for codes and got the p0303 cylinder #3 misfire. wondering what could be the solution for this? I dont think its the coil pack because I had them changed at the dealer from the recall about 2 months ago (anyway to check?) Also I have 97,000 miles on my car and my last oil change I used 0w-40 oil. I know this is probably not the best oil to use at this mileage but I had an extra 5 quarts of them laying around so I decided to use it.

I changed my sparkplugs and coil packs last month. Was getting CEL light but it would go away after a while. I figured out that I had gapped my spark plugs way to small (almost touching) so I took them out two nights ago and regapped/ reseated them.
My car was running fine yesterday, but today when I started my car up, the engine was shaking a lot for about 10 seconds and the CEL was blinking. After 10 seconds the shaking and CEL went away...
It drove fine. I'm just wondering what could be throwing these CEL's and causing the shaking? Plugs are gapped to 0.32
Also, I had my timing belt and water pump replaced almost two weeks ago now. Any chance that could be lending to the problem?
My guess is that one or more cylinders are screwy. I'd rather not bring it into the vw mechanic since I'm tight on cash.
GTI 337/20th Anniversary :: Randomly Lost Acceleration - Misfire When Hit Over Boost
Ive been having two issues with my GLI lately, last week while driving on the parkway my car just randomly lost acceleration, no lights came on but the gas peddle was unresponsive. I was able to restart it while coasting and thought nothing of it. Then it kept doing it. It was raining that night but ive never had an issue before. Other times it dies it is sunny out. The second issue is sometimes when I hit over 10lbs of boost the car will start to misfire and run like crap. No CEL's come on the dash but if we scan it with VAGCOM it says theres misfires happening, obviously. Already did a smoke test and there are no vacuum leaks.

I have Unitronics Stage 2, and a 3" downpipe... I keep getting a CEL P0420. I know its about the second o2 sensor, but I don't understand why I am getting the CEL with my chip? Could it be possible that when I put the downpipe back in i reversed the 2 sensors? Or are they the same...

Car is throwing Converter below threshold code. I figured i would put in MagnaFlow High-Flow cat from my work but didnt know if that would work. The position of the stock 02 sensor is what baffles me.
It seems to me the factory design has the 02 sensor in between 2 chambers. Could I just install this Magnaflow cat and put the 02 sensor after the cat? Can get rid of this code after installing high-flow cat?
GTI 337/20th Anniversary :: 2004 1.8t GLI - Lean Code PO171
I got a 04 mk4 gli 1.8t and I got a po171 lean code and I know it could be a vacuum leak the maf sensor and other things. But when I clear the code it takes a couple days for it to come back on. But when I do clear it and start the car for the first time the car idles read bad almost sounds like miss fire. The when I pull out it hesitates just for a little than runs fine. Could this be a bad or dirty maf sensor? Like I said it takes a while for the cel to come back on.

So I recently (within the last month) replaced my DV for a Forge 007 and my stock air box for an EVOMS v-flow. My cel came on after the DV switch and was throwing the P0420 code at me. Then I swapped the intake and it has been good but I felt like I was running a bit rich and pulled my codes and it now has P0030 in addition to P0420. Why this is? I have 88K miles. Spoke to a mechanic and he says he thinks it is my cat dying. I'm a bit confused since I have a turbo back exhaust.
