EGR disabled and Knocking
I disabled EGR (1b3 set to 00) on my stock '91 C2500 350/A4, 7747. When I
took it for a test drive it knocked alittle during cruise and light throttle
accel. Should disabling EGR cause it to knock? I thought it would run the
same as with EGR on, seeing how EGR adds spark and removes fuel.
