Tune up

The spark plugs are located under the coils. There are three towards the front of the car under the 3.0 plastic cover. The other three are towards the firewall in the air intake plenum. All you have to do is remove the bolt that is holding the coil, I believe it is a 10 mm then you slide out the coil which has a plastic extension going into the engine. You need a ratchet with an extension to remove the plug. Reverse to reinstall plugs. Repeat as necessary. You will need a VERY long extension to reach the #3 and 5 cylinders in the rear.
