Mass airflow sensor cleaner

[PorscheDoc]

I have used the CRC Maf cleaner and the CRC QD electronics cleaner. Both work good, but sometimes the maf is too far gone and needs replacment. Definetly worth the couple of bucks to try it first though. I say I usually end up with maybe 60-40 split on ones that it saves, vrs. the ones that are too far gone.

tape head cleaner is good, too

My car has been running really well, but I did have very slight but noticeable variation in idle speed. This seems to have helped.

Checker auto parts carries a large number of CRC products including the MAF cleaner.
