Frank, by "None" are you saying there is not a proper procedure to reboot the ECU? I replaced the O2 sensor last year along with the OVR. The car accelerates well now, and cold start idle is about 1000rpm until put in gear and then stumbles around 500rpm until warm up. Cleaned the aux air valve but no change. The car has 52,000 miles. Plugs, wires cap rotor all new. Temperature sending unit new. How would one determine the duty cycle?
Any thoughts? Thanks for your input.
