Hi guys my Chevy G20 1992 v8 has had his service some 2000 km ago. (Not with a regular Chevrolet dealer). Now suddenly, when I let go of the throttle, the Service Engine Soon light will come up. When I engage throttle again, it will fade out. After a top, running Idle, it will burn some longer than when it comes up at disengage.
Is this a problem or just a mileage counter that has to be reset ... and how ?
Advice appreciated.
