I have had this problem through a stock motor and a rebuilt one. Bought 2 brand new EGRs and 2 oxygen sensors. Car is 89 wiring all the way through. All smog stuff there. After 30 minutes of driving gives me a 32 and 91 codes. Always O2 sensor and EGR. Every blue moon a fuel pump code. I got a 190 lph in there. Does this sound like wiring, and which wiring/circuit? I have changed heads and intake and still get thise codes. Its smog time and i need to pass.
