Ok, I have an 08 beetle that I'm trying to work the kinks out. Recently started having problems with it dying out on me. It's a 5 speed and it runs fine if I stay under around 3 grand rpm. If I go any higher it looses power, sometimes it dies, most of the time I can just back out of the gas and it will slowly gain power again. I have codes that I got from a generic OBD II and those are P1580, P0411 and P0304b which is number 4 misfire. I have unplugged the MAF and the car wouldn't stay running. Any ideas??
