Error code 32
Hello,
I have a 1990 L89 VIN8. I replaced the fuel injectors, fuel pressure regulator, EGR valve. Car ran perfectly for a couple hundred miles, and then I got an error 13 (O2 Sensor). After I replaced the sensor and cleared the codes, the car still idled and ran just as poorly.
Now I am getting an intermittent SES error light and an ECM error code 32 (EGR related). The only related circuitry is the EGR solenoid attached to one of the thermostat bolts on the front of the intake manifold. I understand that the first thing to check is the EGR sensor/switch, but there is no temperature sensor/switch on the intake to exhaust manifold crossover tube on this engine.
I was going to replace the solenoid but the dealer says it was discontinued in 2006 and local parts distributors can't get one either. Eckler's doesn't list one either.
Does anyone know where I can get a new EGR solenoid or should I be looking elsewhere to correct the error 32 problem?
Thanks,
Ivan

First I would check the vac lines for cracks, secondly you don't know if the problem is the EGR Sol or the EGR Valve. There's a diagnostic method on my site; just ignore the part about the EGR Sw as your '90 doesn't have said sensor.
Once you isolate the problem to the Sol or the Valve your local AC Delco parts store should be able to hook you up.
