I just got done with a Heads and cam swap on a 02 Zo6 And it will start fine when its cold. but after it up to temp it will not idle on it's own for the first 30 sec or so and then its fine. and it has the check eng light on too any one know what to have shut off in LS1 edit to keep the light off ? it has a code 300 eng misfire and I dont rember the # but the other code was for the map. (out of range or something like that)

Have you reduced the first three columns of the ve table?

ok not too sure what the ve table is I'm diging up info to have a better idea when i take the car back to the tuner latter this week. I do know that we played with the start up seting's to match the cold start as far as the throtle opening to try to get it to idle for that first 30 sec that it wants to die when its warmed up.

Man, do a search on this topic. Hundreds of threads already discuss this matter in depth.

Main Ve table at 400-800-1200-1600 rpm levels. Precise scaling will depend on your cam specs (which you should mention if you need help). Likely you have a big cam causing the misfire codes, correct?

Yes its a MTI x1 cam and MTI stage 2e heads. and sorry that I come off as so dumb I'm just very new to GM cars
