Engine Performance problem
1998 Audi A4 4 cyl All Wheel Drive Manual 203000 miles
My Audi A4 1.8 Turbo Quattro has an odd issue.
When cold, it starts and runs fine. After a drive where it gets to temperature, if I let it sit for a few minutes, it will stall randomly while driving.
When moving off at the lights, or if I hit a bump and it is warm, the engine loses power or stalls. It only does it when it's warm.
I have replaced the MAF, Ignition control module and I have stripped back the wires to check for issues with the wiring harness. Nothing so far.
The vag com reports that MAF sensor readings are out of limits and this error happens instantly the engine stumbles.
It's definately a heat related issue, but for the life of me I can't understand where it is.
have the same problem?
