Service Vehicle Light 2000 Pontiac Firebird LS1 Automatic. Service Vehicle light comes on NOT the service engine light comes on in park and in drive the goes off while driving above 40 MPH after the vehicle was tuned. There are no codes. Anyone have that similar situation?

Sometimes if you turn the MIL of for certain codes, but leave them reporting errors, they set the service vehicle light. its not all of them, but certain ones will do that

I know for sure the rear oxygen sensors. Not sure about others. You just have to make sure you tell it "don't report an error", not just turn off the MIL. It's two separate things in the DTC table
