Illumination of the Check Engine Light may be the result of a loose or worn gas cap.
The spark plugs should be replaced every 100,000 miles. Our technicians recommend replacing the spark plug wires also at this time.
You may be able to prevent transmission problems by servicing the transmission and inspecting the fluid every 30,000 miles. If the fluid is dark or burned, the transmission system should be completely flushed.
1999 Oldsmobile Silhouette Questionshow so I change the check engine bulb? (1 answer)
New GM engine with 2k miles runs perfect after warmup. I'm a little worried that whatever is wrong may finally end up with engine not starting as part wears out. This condition causes no codes to be set. Thanks for any help.
