Here is the beef. I've been having this intermitant Code 32 (EGR on fuel injection). I have done this , Replaced with Original Factory GM EGR for stick, new gasket. New exhaust header,O2 sensor, and gasket and doughnut seal. What else should I be checking? I've checked all the plastic hoses that connect to the EGR and around the Injection unit. All are solid and non leaking. Its starting to piss me off.
