I have followed experiences of people who have cleaned MAF's a couple of times with success, then eventually, cleaning no longer works. They simply go bad with time and use and will require replacement. Try a no residue electrical contact cleaner spray.

Could be the insulation on the wiring going bad and causing shorts. Read this...

My slight surging problem (and the occasional Check Engine Light) went away after this and the ETA rewire.

Gentelmen, Thank you. At the cost of a new MAF - I think I'll try the Elect. cleaner first.

Fyi

Cleaning the Mass air unit with Elect cleaner seems to have worked so far. If that was my problem the check eng light has not come back on. Once again thank you.
