im having a issue with my car keep stalling after awhile. its a 99 z28, I just did a header and cam swap, and now I have this issue of the car just dying on me after a few minutes of driving. Im thinking its heat related because after I let the car sit for a few minutes, sometimes 10-15 minutes, the car fires right up and drive good for a few minutes then dies again. battery voltage is low while cranking, but doesn't slow down the cranking at all. and while driving the gauge shows 13 volts and the ect is not high. I have not got a tune yet, the car wont even make it 5 miles without dying...its a small 220 cam. I have heard that the icm can be intermittent when it gets hot, but where is the icm on a ls1 Camaro? I didn't know it had one. the engine bay gets pretty hot since I have a Sunoco hood that doesn't let heat escape very good. im stumped and would really like some help please. here are my files to show how it happends. its around 3:50.
