SES Code 32
Tried this in the tech forum with no luck, maybe someone here can help:
"I've sorted out my SIR code 16 & SRC code 42, now on to my SES code 32.
I have a '90 coupe L98, all stock except previous owner installed what appears to be MAMO cat back exhaust with crossover (2.25" pipes).
I'm getting an intermittant code 32 (EGR) and wondering if the reduction in backpressure due to the cat back exhaust could be causing it? I smogged the car (Calif car) a month ago and all emissions were a fraction of the allowables both at idle & 2500 RPM tests. Just wanted to check if this exhaust could throw this code before I go through the diagnostic tree. Seems to happen at medium to heavy throttle, but only intermittingly.
Thanks for any input. "

Thanks Rick for the reply. I don't think the '90 has a switch, just the solenoid & valve. I'm going to check the solenoid & valve per FSM and see if I can find a problem. My guess is it will all check out OK due to the intermittant nature of this code & the fact it tested great when smogged.
