Re: Loss of power Need Help!!! (geraldc70)

Cleaning the MAF won't do anything. If it is bad, eventually it'll throw some codes for fuel enrichment at maximum amount. It's a PITA to diagnose, because all of the numbers (airflow, etc) will seem right. Find a known good one, toss it in, clear all codes, and see how it runs.
Code clearing may have to be done with VIDA or similar, not sure if the OBD2 ones will also cause the adaptions to reset. Never tried.

I battled this problem for a year. Kept looking for a vacuum leak. Tried "cleaning " the MAF. Then one of the guys at my local dealer lent me his "test" MAF, and did the above. Problem solved.
