ECU won't communicate
I have a 92 non-turbo and I had a lot of trouble with different thinks not working right. Like the cooling fans never came on and the idle was about 2700rpms. So I replaced the ECU and everything started working great. But for some reason once it warms up and idles at 800rpms the check engine light comes on. I sent it to the shop and they said the ECU won't communicate. Anyone ever had this problem?

RE: ECU won't communicate
I have a 94 stealth that once it got warmed up it would shut down. once it cooled off it would start again but once it warmed up it would quit running. After having carefully checked out it turned out to be the ECU. I had it rebuilt and all has been fine since.
