Hi,

Performing a tune-up on this engine isn't too difficult to perform. Since each cylinder has its own ignition coil, you don't have to worry about ignition cables (spark plug wires).

To get you started, here is a link that explains the procedures related to spark plug removal. Additionally, it covers a few general maintenance items that should be serviced when a tune-up is completed.

If you look at the attached pics below, they provide the directions specific to your vehicle for spark plug replacement.

As far as servicing the throttle bore, here is a link that explains how it is done:

Let me know if this helps or if you have other questions.

Take care,

Joe
