Im a beginner Got a 2005 chevy 2500hd 6.0ls gen 3 engine did a cam swap seem to have the maf and sd dialed in just at idle its not wanting to stay running i tried bumping the idle target up its still not helping can someone help me with the idle tuning.
Can you monitor your IAC steps? Is it just in neutral or in drive? Or both? How do your idle fuel trims look? What size cam?
Also look into the spark tables in the idle area. When i did my cam swap in my '13 Camaro SS I had to bring down the spark tables in the idle area for it to start and run
