1993 Chevrolet G20 Sportvan 5.7L Excessive Emissions, Hesitation
When trhottle is opened, ECM commands EGR solenoid to 100% duty cycle. MT2500 scanner shows EGR position at 0% no matter where EGR is. Computer does not see EGR open so it continues to drive it 100% causing driveability and emissions concern.
