    Generating code 32 - EGR curcuit

    I have a 1989 GMC s-15 with a 4.3 "Z" backed by a 700 R4 tranny. The truck is generating a code 32 while driving at highway speeds (65mph). I've checked the EGR valve and it's ports and they are clean. I just replaced the EGR vacuum solenoid but it's still generating the code. What else should I be looking at?

    Map sensor? maybe vac leaks,open circuit or maybe even the ECM.

    You need a chilton or haynes manual so you can follow the diagnostic chart, it will show you what and where to test for this issue and hopefully help cure the problem. maybe someone can scan the code 32 diagnostic page for you here
