On a 1997 Oldsmobile Achieva SL, the spark plugs are located on the engine, beneath the ignition coils. To access them, you typically need to remove the engine cover and the ignition coil pack, which sits directly above the spark plugs. The spark plugs themselves are threaded into the cylinder head and can be accessed once the ignition coils are removed.
Remove the four bolts on the cover plate and lift straight up exposing the wiresets.
