1992 C4 Engine Missing, ASR, SYS - Codes / Input?
My neighbor has a 1992 Vert and he has a "Service ASR" light, "Check Engine" light, Flashing "SYS" light and a terrible miss. Car won't run smoothly and seems to red line at around 3,000 RPM. I did some research here before posting and most outcomes look like a computer. Battery is new (just replaced today) and here is the code list:
Module 1 - C41
Module 1 - H41
Module 4 - "Err"
Module 9 - H65
Module 9 - H72
Can someone point me to some troubleshooting steps? It would be much appreciated. I read two pages of "Service ASR" posts and I'm thoroughly confused. Also, is this the EBCM computer that usually is the problem? Who on the forum can rebuild them?
Thanks in advance for your help!
