How do you change spark plugs in a 1991 Pontiac Grand Am?

Need more info! Which engine do you have?? I would guess at a quad engine since you can see the V-6 plugs!! There is a cover that says QUAD 4 on it. There are 4 bolts that hold the cover down that need to come out, and 4 connectors that are the plug wires that need to come off, then you can change the plugs. On the older quad engines, the plugs were known for pulling the treads out of the cylinder head! If you have a plug that is exceptionally tight, don't remove it unless you know what your doing! It can result in cylinder head replacement!! Good luck!!
