'94 Cherokee 4.0L Tune-up tips requested by semi-newbie
 

The subject says it all. I plan on tuning-up my girlfriend's 94
Cherokee. Plugs, wires, fuel filter, and distributor cap. I plan on
going with regular run of the mill name brand parts. The odo is at
240K. Is there anything I should know? I'd appreciate any little
tricks or suggestions anyone has to share. Other than replacing a
water pump, I've never worked on a Jeep before, thus the semi-newbie
status.

Geez! What passes for a tune up these days. No points, no carb
adjustments, not to mention a valve adjustment.

But sence you mention it, you probably will not want to tackle the fuel
filter, and unless you are having trouble I wouldn't. But I WOULD do the
AIR filter and Rotor while I was at it.

You will naturally get differing opinions on brands. I prefer Bosh
platinum plugs, Mopar® wires, cap and rotor. Fram is fine for air filters.

A trick I use ... if it ain't broke, why fix it (does not apply to
preventive maintenance items ... fluids, filters, worn tires, worn wiper
blades, worn rotors, worn brake pads, ashtray overflowing with loose change,
backseat overflowing with ... well ... overflowing ... ). In other words, if
you check the plugs, high tension wires, distributor cap and they are good,
why replace them?

I second Bowgus' opinion.... if it works, don't fix it. I will go a step
further, and advise you to stay away from Bosch platinum plugs. They will
take a perfect-running engine and make it run like crap. Not just my
opinion, it has been proven over and over again in my service bay, as I toss
them into the trash and replace them with 79 cent Champions.
