So right to the issue.

The car runs fine until it reaches operating temp (199-203f). When left idling for a bit it will smoke when I hit the gas. The car runs a drives fine, but when I really get on it once at temp it jerks and bucks horrible! My cylinder 1 plug seems to get fouled out (tried switching the coil packs around, same outcome) but the other 3 seem good. However I get a code for misfire cylinder 2. Boost seems good, doesnt run better with maf unplugged, have 2 new injectors (thought that may have been it). Just seeing what other ideas you guys might have! Thank you in advance!

Default Welcome to Volkswagen Forum - Rules & Recommendations

I've seen the same question on other forums I use.

You need to get your motor scanned (preferably with VAG-COM\VCDS) for any error codes logged in the ecu and post them, that will save a lot of guessing and check systems out.

 

Sorry I dont know how these things work just always see threads from here when I look up issues. I'm definitely going to keep up with this forum, its helped me with a lot, and now I can possibly help others with some of the repairs I've had to make. This is my daily driver, but also a toy. I did scan it, I get a code for: misfire cylinder 2, mass or volume air flow circuIt low, and vehicle speed sensor range/performance. If I unplug the MAF it doesnt get any better.

 

Which scanner did you use to find the error codes a generic scanner?

I would suggest you join a great VW forum http://www.volkswagenforum.co.uk/forum.php is far more active than here.
