Car wouldn't accelerate

[JaMoeR]

I have this problem since I chip the car with Oettinger. Sometimes when I am cruising on the final gear the car just stop pulling. The RPM goes down as if you release your accelerator. I cannot rev it up even though I floored it. But once I put into neutral then I can rev again. The dealer told me its the Air Mass Meter that is playing so they change it under warranty. It was running fine for 3 weeks then the symptom is back. Anyone ever had this problem b4?

chage your mass air flow sensor again... sounds like something it would cause..

or possibly a boost leak

vag it i guess...or take logs to see whats going on...

Try to drive the car w/ the MAF disconnected (be sure not to mash it too hard though). if your idle stablizes and your problem goes away, 99% chance you have a boost leak.

Good Luck

The problem is it does not happen quite often. Maybe once a week at most. When the first symptom appear I did VAG it but there is no error recorded.
