Where are the spark plugs in a 1989 Pontiac Grand Am?

The spark plugs in a 1989 Pontiac Grand Am are located on top of the engine, under the valve cover. Because there are several engine options for that year (likely a 2.5L four-cylinder or a 2.8L V6, possibly others in lesser numbers), the exact placement will vary slightly depending on the specific engine. You'll need to consult a repair manual specific to your car's engine to get the precise location and access instructions.
