Going to do a tune up on my new used YJ

[sixdoubleseven]

I'm going to change the plugs, wires, air filter and maybe a couple of other things. I'm going to bring it to a garage to do the oil since my landlord wont let me do it in the driveway.


My question.

Are there any plugs and wires that work better for the 4.0L or should I just go with some cheapo Champion plugs and no-name wires from Lappens?

I tried searching and only came up with some Bosch Platinum's on someone's "goodies" list.

Thanks,
Dave

I would just buy a good quality cap (brass terminals), rotors, wires and champion truck plugs for the applicaiton. You are looking at about $40 out of your pocket. I bought the cap (vented) and rotor off Advance I believe cant remember the brand and the Borg Warner wires from Pep Boys.


If you want to be really adventurous, and spend big you can buy some high voltage kits that let you run a little more gap but IMHO they are nice but not worth the money.

I've been using champion plugs on my YJ sinced I got it. You can go with performance plug wires like Jacobs, D.U.I., Splitfire or other brand if you want to spend extra for it. As far as tune-up goes I just do the basic thing, change the spark plugs (be sure to gap them), new plug wires if they are old and looking worn-out, distributor cap, rotor and just the timing (you need a timing gun for this).

GoodLuck

i use mopar wires/cap/rotors.. it cost me 45-50 for everything. Only 10 bucks more than a normal store. Plugs i used champion plat. ones and replace them once a year like clock work. I've got 181,000 miles so something must be working....

So I changed the plugs and wires on Saturday, took 25 minutes. I used $1.99 platinum plugs and a set of wires for $24.00. The old plugs weren't too bad. Some were a little burnt, the gaps on the old plugs were what they should have been. The old wires weren't bad either, except three were one color and three were another color, so I wasn't sure if they were the same brand. The Jeep feels like it runs better, however, it could all be part of my imagination.

I have tomorrow off, waiting for couches to be delivered, so I'm going to get my oil changed before they get there. Are you guys just using basic, non-synthetic, 10W-40 in the summer? That's what I had planned to have the garage put in.

The air filter looked recent, so I didn't bother changing it. And I'll have the garage check and adjust the timing.

The radiator fluid looks very clean, so I'll leave that as it. I would like to have the differential fluid changed as well as the transmission fluid, so if anyone happens to be in Massachusetts (Waltham, Watertown, Newton, Belmont) knows of a good place to have that done, please let me know.

Thanks to all with your advise.

dude if you lived near MD i'd do it for you for a case of beer.

if you can change your oil you can change the fluid in your diffs and tranny. Nothing to it. Just a bunch of bolts. Even if you remove the pan from the auto and change the filter its pretty straight forward. All you need is basic tools.

When/if you do your diff. remove all the bolts except for the top one. Loosen it and then use a small hammer. Hit the side of the diff. and have a pan under to catch the fluid. It will slide off to the side and is much easier to break the diff seal than trying to pry the thing apart. All you need is to let it drip out, use a razor to clean both surfaces, apply a bead or rtv, and bolt it back up. Add gear oil till it starts to poor out of the filler and then seal it up, done. Repeat for the front. Tim

doing basic stuff like this makes you more knowledgable in the future if you have bigger problems. its how i started. Tim

Tim, I'm confident I could change them myself, however, I can't do it in my apartment parking lot or at my parents house (neither will let me). I used to change my oil myself all the time, but it to be a pain to get rid of the oil and for $20 I'd rather let someone else dispose of the oil. Thanks though, and if you were closer I'd give you multiple cases of beer to do it for me.
