Clear then, drive around see which ones come back and post it up. None of them are to serious and some may have been a one time problem.

cleared the codes and realigned the throttle body started the car, check engine started blinking.
scanned
p0301 misfire cylinder 1 misfire detected
p0304 cylinder 4 misfire deteced
p0420catalyst efficency below threshold(bank1)
p0300 random multiple cylinder detected.
What I am thinking is its the MAF because it keeps throwing random codes. Then when I took the unplugged the MAF and started the car, it started normal and no codes thrown. I think the MAF might be gone. Anybody know were I can get an MAF for an AWP at a good price?

Try a place called WORLDIMPEX.com. There where I'm getting mine for my Jetta. Prices are pretty good. But i would even try Autozone or something like that.

I started the car with the maf unhooked and the car started and idled fine, with no cel. If it was a problem with the cat wouldn't it still misfire even with the maf unhooked?

they have one for $55 that is "known to work" with most 1.8T's, and I have heard that it almost always does.

You drove to autozone with a blinking CEL!!

MAF shouldnt cause the cel to blink, the misfires will do that. Coilpacks ok?
