O2 sensor replacement / ECU "break in"
Changed my O2 sensors today as I think it is related to an intermittent cut out issue I'm experiencing and it running lean/backfiring.
Question: After replacing O2 sensors in a 1994 NAS D90 does the ECU need time to adjust to the new sensors?
Reason I ask is it is experiencing a little cut out of power (But different than I was experiencing before) after test driving it. I drove it for about and hour this afternoon and it did it a couple of times.
