today my 1993 C4 was dead when I turned the key but I had plenty of battery. I removed the ICM and it was HOT after a 48 mile trip. The car had sat about 2 hrs while I visited a friend and wouldn't start when I got ready to leave. I removed the part and let it cool for around 30 minutes and put back with new heatsink paste. The damn car started and I drove it back home. I almost used 1 of my AAA tows for nothing. Hope this helps someone out there in C4 land.
