Need ODBII Drive Cycle for 97Z28
Need ODBII Drive Cycle for 97Z28
My attempts to pass smog seem to be futile...
I still have not managed to trip the 'Complete' flag for O2 Sensor or Catalyst. Does anyone have the actual drive cycles for these 2 tests.
I believe one is the drive to 45mph at part throttle and hold it for 5 minutes, then decelerate to 0, and hold the brake for 2 min?
Would like confirmation, and ideally, the actual step by step from the book.
Thanks,
Keith
