If you have a bad egr valve or egr related problems, besides a SES light what kind of symptoms can I expect? Im just curious cause when Im cruising on the highway at around 110kmh my SES light sometimes comes on. The car doesnt run any different and the light will go out if I shut her down and restart her. I was told on another board that its most likely a code 32?/EGR. Its a new EGR with about 1200kms on it now. Its on a 5.7L TPI 91 Z28.

 

I replied to your question at IROCZ-Post on how to check codes and supplied a link to a Code 32 tech article at thirdgen.org. Check it out!
