I'm need to change the spark plugs but can't get to them. The car listed above has a 3.8 fuel injected. I can see them but can't get to them.

Good morning,

The plugs in the back are tight to get to. You need to go from the side to access them at the back. You will need a 5/8 spark plug socket, a 1-inch extension, and a 3/8 long handle ratchet.

It takes a shop a good 40 minutes just to replace the rear plugs. Twist the wires and then remove them to avoid damaging them. Then once you break them loose, you can spin them out easily.
