have you scanned it? sounds like a bad sensor since its only happens when it warms upHey guys, I need help. I have a 94 trans am that just started stalling on me. I already changed out the ICM twice today. The first time I changed it, it still died when it got warm so I took the ICM back to exchange it for another one and that one worked better. With the second one, I was able to let the car idle for 30min then drive 8 miles to get home and everything was fine. I let the car sit for an hour, then when I tried to drive it, it stalled 2blocks away. I have a spare coil so I'm going to try to put that on tomorrow. Is there a way to know for sure if its the ICM? Also, this morning while driving the rpm's would drop from 2000 to 500 for a few seconds then go back. It did that about 3 or 4 times. Anybody have any suggestions?
