Question type: Maintenance & Repair

lean. The idol runs high And low or surges.  I do not know what to adjust because it's all electronics, please help

1 Answer


Sounds like an O2 sensor issue. Before you change it however I would go to your local AutoZone and have them extract the codes. They will do this for free. If you are close to the 100,000 mile mark I'll bet O2 sensor is bad.
