gregers Posted November 17, 2011 Report Posted November 17, 2011 have you taken a look at the maf? Quote
jordan1 Posted November 17, 2011 Author Report Posted November 17, 2011 ive tested the car on my snap on fault finder dosent find a fault, ive orderd vagcom to test itits strange though cause its fine for about 2 miles then the engine gets warm and losses power but if you jack the car up and give it some when theres no load it seems to be fine??

seatkid Posted November 18, 2011 Report Posted November 18, 2011 As Gregers says the MAF sensor is the no.1 suspect. MAF sensor failure does not show up on diagnostics. Quote

Davehillbo Posted November 18, 2011 Report Posted November 18, 2011 do a search on the forum,ON MAFS.then decide if you agree. Bizzare that disconnecting the MAF makes the car die :s, i wouldnt have thought the maf would cause the problems you are experiencing. Quote
