tune up

[Sblanck]

What all is needed to tune up a 4.0L jeep

Last tune up I did myself was on my 69 Caddie
Things have changed since then

Thanks

Pretty much just the spark plugs since it's equipped with a coil rail. If you are so inclined to do a good engine tune up, might as well check the t.body and see if it can use some scrubbing.

Excellent

Thank you

be gentle on the coil packs as they are expensive!~
