Ltrim's 25% at idle??? I have the usual head/cam/intake and upgraded inj.'s mods. I keep throwing P0171 & 174 lean bank 1 & 2 codes. So I throw ATAP on and find that my idle is at 25%(super lean).
At one point it went to 9.4% and stayed there for a while and then went back up. My MAF rate was .96 at idle. Misfires on cyl.'s ranged from 1-10 on all at idle and went away with higher rpm. No knock retard at all.
Ed Wright did the PCM could he have deleted the Knock Sensor? Looks like a vaccum leak, but where do I start know? Thanks
