MAF Sensor success story

[dean1969]

I feel obligated to post this so that others might benefit and save a few dollars. I have a 98 Blazer LT that had a strange hesitation problem on startup, including lack of power at full throttle. The trouble codes I was getting were left and right bank LEAN. The car even died at random on occassions. The dealer was unable to diagnose the problem. All they said is "You have a MAF sensor fault." Knowing it was running lean, prior to my dealer visit, I bought a new fuel filter, O2 sensor, and fuel pump, totalling over $500. Well, as it turns out the only thing that was wrong is the fact that the MAF sensor was dirty and needed cleaning. I pulled it off the car and CAREFULLY cleaned the 3 small wires with Q-Tips and Alcohol. They were coated with black goop. After cleaning the MAF sensor all problems have disappeared. So, the gist of this story is I spent $500 when all I needed was 30 minutes of my time and a 2 cent Q-Tip.

Ive been reading about alot of fixes with Q-Tips LOL

Strange your Auto can benefit so much from something thats designed to remove ear wax

Or an even safer approach is to not touch them at all and just spary the filaments with brake cleaner.

Works like a charm.

Be careful cleaning the filements, they are very very prone to breaking.
