Car runs fine until it warms up then goes crazy.....help.
95 Z28 Camaro.....cranks fine when it's cold then after it warms up....about a mile down the road.....starts spitting and backfiring....shoots flames out the tail pipe.....shuts off sometimes.....will eventually get you back home but it's a battle.
Ran code check with a laptop and ALDL cable from a friend had six codes including ESC grounding problem, MAF, MAP, Knock sensor and others.
Has new ac delco opti. New coil, new MAP sensor, new temp sensor and new plugs.....changed three times in two weeks.
Running so rich it fouls the plugs.
Car has only CAI, air foil and Headers. That's all.
Everybody respond, I need all ideas.

Did you check your O2 sensor voltage. I just scanned a buddies car that is doing something similar, and I noticed his 02 sensor voltage is different by .5 from one to the other. It hasn't been fixed yet, but I'm supposed to talk to him today. Let us know if you notice anything funny with the 02's.
