1997 GMC C1500 Sierra SL 5.7L MIL Lamp on
Posted to GM Driveability on 1/17/2007 10 Replies

The MIL lamp comes on every month on this vehicle and the owner thinks there is a big problem. The OBD II scanner erases the code and turn the MIL lamp off for about a month. What can I do to stop this? My thought is to replace the O2 sensors or cat.
