I would like to document this for posterity. I gave my 2001 Dodge Stratus R/T a tune-up over the last few days. It hasn’t had new plugs or wires in the last 100,000 miles, and I figured it could use some care if I was going to have it hit the 200,000 mark (currently at 130,000). Anyone seeking to do such a tune-up on this 3.0L Mitsubishi engine be warned that it’s fairly involved. The spark plugs are under the plenum, which means the plenum needs to be removed, and all the wires, sensors, cables, etc that attach to the plenum also need to be removed. Further, if you plan on replacing the distributor cap and rotor, you also need to remove the battery and battery tray. Note: I recommend replacing the rotor and cap, as mine were quite worn after 130,000 miles. I may post pictures later.

If you do want to do continue, I’d recommend bringing a laptop along and following this site: http://home.pacbell.net/fong8/gstuff/tjc_plenum.htm . It has very detailed instructions and pictures to show all the bolts that need to be removed.

Finally, anyone following along in the Haynes Manual* be warned that the order on the cap indicated in the book on page 2B-1 may be wrong (it is in mine, I don’t know if it’s been fixed in later versions). My manual showed firing order 4-2-6 top-to-bottom on the left side, and 5-3-1 on the right side. It should have been 4-2-6, 3-5-1. It was printed correctly on my distributor cap.
