850 idle/hesitation: You dirty little MAF!

Post by mwy »

Thanks to the tips on this website, a little electronics cleaner goes a long way. I was having an occasional dip in idle, and sometimes serious hesitation between 1800 and 3500 rpm. After 3500, it would kick in and take off. Since my fuel filter and pump were new, I knew it was getting gas.

Cleaned the MAF with electronic contact cleaner, even though it looked clean and everything seems to be back to normal.
