Yo...I've been having misfiring problems for a few weeks now. I changed spark plugs and took a bunch of VAG readings. The misfire is in cylinder 1. It happens under WOT really bad -- especially when the turbo is spooling hard. The problem is either carbon deposits, coil pack, throttle body, clogged injector or ignition. Anyone have experience with this? I am working on th car as we speak. Someone mentioned something about having misfires due to an improper TB adaption. I have run my stock and APR ECUs and let them adapt many times, but he said something about some kind of VAG codes to re-align it. He didn't sound too sure of himself though. However, I noticed a DTC saying something about a bad adaption, but I can't get it back. Anyone have any experiece or ideas? HELP!

Thanks,
Jon Ghenn

Could you swap coil packs? See if it follows that. Then try injectors.

Jon G

how do I swap the packs? What's that metal peice do?

CharlieGSanD

if it follows the coil, then that is the problem, if that doesnt change anything, pull the fuel rail & switch the #1 injector with another & see if the drtonation follows the injector... this should either show you whats wrong or @ least it will narrow down your problems

CharlieGSanD

got a bently manual?

Jon G

misfire followed the coil pack to # 2.

Just to verfiy, try finding someone local to borrow a coil pack from.

*knock* *knock*
Jon G: Hi, I live next door, would you happen to have a coil pack I could I borrow?

neighbor: No, but we have some sugar.

Jon G

did coil packs change from earlier 1.8Ts? I have a '98.

Again, not positive, but you could always ask him to read off the part # on his coil pack and compare to yours.

just pull it off the coil pack. They have a built in resistor which go bad first. Coils themselves are hard to break. Cheaper too.
