One month ago I had the "Service Engine Soon" light coming out in my 2002 GMC Envoy. I had driven the car to the repair shop. The diagnose was "EVAP system error", they conficed me that such type of problems is caused by oxygen sensor. After changing the ogygen sensor, the light is still on and even stronger (lighter). I was provided by too many guesses for the cause of the problem. Can you help me guys to find out why the "service engine soon" is still on?
Thanks in advance
have the same problem?
