I was curious to know which issue causes worst fuel economy on a 88 fiero formula a o2 sensor or faulty Egr solenoid, I currently have code 32 goin on when freeway cruising but have no issues with how the car runs but I notice that I have very poor fuel economy and was wondering if a faulty Egr solenoid really effects it that much or could it just be a lazy o2 sensor.
