Hi guys, my 2000 S4 was down on power, running rough ect so took it to my mechanic (I suspected a faulty MAF) but he couldn't find anything wrong with it! So I unplugged the MAF and the car ran perfectly, that would suggest goosed MAF. I've just installed the new MAF and now the cars power is back but the idle is lumpy as hell. It just keeps bouncing between 1-2000rpm and if you put on AC it almost dies. I've unplugged it again and it drives great but I would like this sorted as with it unplugged the dashboard lights up a few warnings. Any ideas what could be the problem and also is it ok to drive with the MAF unplugged cause I'm heading to the Highlands on Saturday via the Old Military Rd so there may be some spirited driving! Cheers.
