Engine Missing

I swaped back out the proms again and did not help. SES light is still on at startup.
I may send my ECM to Tom Henry and have them send back to GM for remanufacturing. 30 day process.

Well after several months of waiting to find a ECM a kind ZR-1 member finally helped me out. Scott Collier sold me the one he had just bought off of ebay. Thanks Again Scott!
It was a 91 ECM. I put the Marc Haibeck PROM in it and put it in my 92.
Initial start up no SES light. Power Key was on like it should be with the PROM from Mark.
The car ran great. I took it for about a 20 mile drive. Now I know why I bought the ZR-1. They are really fun cars to drive. I did blow the cob webbs out of the engine.
Now I plan on sending my ECM off to get rebuilt.
Thanks Too All that helped.

I just recently read something written by Marc Haibeck (maybe on his web site?) that he has a source to get the ECMs rebuilt. Not shilling for the guy here, but FYI - just another source for ECM repair to tuck away, just in case.

Glad to hear the ECM worked for you and your beast is finally fixed.
