Thread: Running pig rich and stalls when warm

with a aftermarket maf? if so either get it replaced, or best bet is to get a used one from a junk yard, they run around 40 bucks and have a 60 day warranty. my jy maf is 4 years old now. best 40 i ever spent.

i think whats happening is it runs fine cold in closed loop, ( runs off the pcm) once warm its in open loop running off the sensors. and the maf is crappy causing it to run badly.

I'm not sure if it's aftermarket, it's from a local parts store and not oem. Yeah this is the second new one. They replaced the first one under warrantee after a month. As for the junkyard, ours are out to lunch on their pricing. Sometimes I can buy new from napa for the price those crooks want.

edit: my tuners going to do me a sd tune.
