2.3L dual plug 4 cylinder.

Metro, I like the convenience of having a truck, but I don't want to sacrifice the mileage like I had to with the F150. Also for trips to the Pick and Pull, and the county recycling center with yard debris. and auctions when I might pick up something for a good price.

Be back later. Thanks for the interest everyone.

Im not sure if anyone has brought this up, but on the dual plug 4 cylinders 1 plug fires on the power stroke (when there supposed to) and the other fires on the exhaust stroke. it is supposed to help with emissions, but if you rewire it they will both fire in the power stroke (like the hemi) witch renders a more even detonation giving you more power and fuel mileage!

I did the same thing on my old 91 mustang

It takes no tools, just about 40 seconds.
This is how its done if you wanted

Step 1: open your hood and locate your coil packs


Step 2: on the FRONT coil pack.....(the one with wires going to the drives side of the engine) label your wires so you know which ones they are
here's a little diagram just in case

1 3


Step 3: remove all 4 wires and re-install them in this order...

4 2

Step 4: profit
