Need Help motor idles but wont revup( Got data log posted ) Ok so i have been searching for 2 nites and nothing....heres the deal 5.3 ls1 intake modded my stock harness ls1 hotcam 30# ford redtops lt headers 2000 chevy pcm t56 trans tuning done by lt1pcmtuning. I got 58psi at the rail car starts kinda hard but idles as soon as u touch the throttle it tries to die. It stumbles constently if u hold it open it pops threw the intake if u tap it it will eventually revup but once then it gets up to 1500rpm and the injectors just cut off and once its back down to the idle they come back on (noid light) oh and its running really rich. It will idle all day fine. Goin crazy need some major help also its in a 67 camaro.
