Do you have a mechanical vacuum gauge hooked up?
01-13-2013
im trying to get one
01-13-2013
i have a lsm1 scan tool are there any other values that could help

MAP should read around -19 to -20 at idle.

bad map sensor, i guess i wont know till i get a vacuum gauge

Have you checked fuel pressure? It could be low and attempting to fuel it more due to lack of fuel pressure.. Also could have low fuel volume
01-13-2013
fuel pressure is good round 55 psi i have a map sensor of a 3.4 l im gunna try tommorow. just gotta get the connector to go in. and im gunna get that vacuum gauge and test that

well map sensor is good. i deleted the egr today and now rpms bounce like crazy at idle, but my map reading is where it should be. i unplugged the MAF sensor and it smooths out at idle and will sit at 1500 rpm. is it time for a new MAF sensor?
01-21-2013
Tried cleaning it yet?
01-21-2013
ya ive cleaned it 4 times now
01-21-2013
Know anyone around that'll let you switch out mafs to see if yours is actually bad?
01-21-2013
