I put a lower grade gasoline in the engine after purchasing the pre-owed car and not knowing of the fuel requirements. Check engine light illuminated several times while operating on lower grade fuel ('89). Engine also rumbled when near idle or in neutral. Drove until tank emptied, replaced tank with proper grade fuel and problem went away.
