45 psi at idle ..you mean check it with with vacuum to the pressure regulator off?




I thought about grabbing a few from the junkyard, but they take them off the cars and want 80 bucks a piece for them. I may buy a used ac delco maf and take the one I have back


I bout a cheaper aftermarket maf at start up it would rev up on its own for a few seconds.. and periodically hesitate/stumble.I sent it back.

I then bought a new car-done unit (Its only a few weeks old.) It helped with the start up problem but hesitates/stumbles just the same as the other unit. I will probably return it and get a used ac delco and hope it works ..three's a charm right? lol


They want 80 bucks for the maf at the junkyards near me.
