Where are the spark plugs located on a 1997 Buick Skylark?

The spark plugs on a 1997 Buick Skylark are located on top of the engine, under the plastic engine cover. To access them, you'll need to remove the engine cover. They're arranged in a V-pattern following the cylinder head layout of the engine (likely a V6). You'll need a socket and possibly a spark plug socket extension to reach them comfortably. Consult your owner's manual or a repair manual for a diagram showing the precise location of each plug.
