My 1992 had an ECM problem recently. I sent it to Cardone and they repaired it. Put it back in my car and I have been driving it for over a month with no problems.

Another success here. Replaced ECM + EPROM and the car runs perfectly. What I thought was suspect injectors turns out to be the computer doing strange things.

Looks like these 1990-1993 ECM/EPROMS do start to breakdown over time whether through vibration and/or heat.

My 1990 runs like an absolute dream now. Feels like it can re-run the 1990 Corvette Endurance Epic running the L98 six hours at 170 odd mph.
