I own a 92 Corvette coupe in great condition - when it runs! I can start it when cold, but then the check engine light will come on after about 10 minutes along with the ASR light. Then, the engine won't run over 3,000 RPM, the coolant fans come on, the AC stops, the speedo stops working, and it goes to a high idle and it runs rough.. This behavior won't go away until it cools down.
It is also throwing a C41 code in the 4.0 computer. This code could be anything, and it points to a bad connection between the ECM and the CCM, but I had the ECM rebuilt. Tore into the dash and can't see anything unusual in the wiring.

Has anyone else seen this kind of behavior? If so, did you solve it?
Would appreciate ANY ideas. Thanks in advance.

 

Asr is the Anti Slip Regulation system. You probably have an issue with the abs system. When this happens it throws the engine into limp mode, (limited throttle,fans on, no a/c etc.) A good code reader may be able to tell you which sensor is bad.
