2002 GMC Envoy 6 cyl Four Wheel Drive Automatic 195000 miles
Our Envoy had the check engine light come on and started to idle rough RIGHT after my husband changed the oil. We took it to AutoZone and the code said the Cam Shaft Sensor needed to be replaced. That didn't help. It seems to be better after it warms up. It only happens when the car is idling. Once it is up to speed, it runs great.
have the same problem?
