How can I change the spark plugs on the 3.1L engine?

Asked by Gimril Jun 12, 2007 at 08:32 PM about the 1997 Pontiac Grand Am 4 Dr SE Sedan

Question type: Maintenance & Repair

I can see the spark plugs in the front, but I cannot see the 3 in the rear of the engine.

My issue is that I have this car with 90000 miles (plugs have never been changed) and getting a Cylinder 3 misfire code. I can see the wires go under the ignition coils (I am assuming that's what they are), but have no idea how to get to those plugs.

Please help

On the top of the engine there should be a cover shield that is held in by 4 screws. If you remove that and take the plug boots out you should see the holes where the spark plugs are.
