Hello

Hello everyone, I wondering if any of you have links to sites or videos on how to do a tune up on a '99 TJ. I got a mopar tune up kit with distributor cap, rotor, plug wires and I have spark plugs. Any help would be appreciated, thanks!

I would try the Chilton or Haynes manual if I were you...

thanks, I have the Haynes manual its ok, but not as descriptive as I thought it would be.

Not trying to sound harsh, but all you do is pull them out and replace them. Make sure the gapping is correct on the plugs though. That should be listed somewhere in your Haynes manual. Just put it back together the way you found it. The firing order for the cap should be listed in the manual too. The rotor only goes on one way, and just use common sense when placing the wires, longest to the furthest distance,, shortest to the shortest distance. The one with two bent boots goes to the coil.

Like Corrupt said, it is not so difficult;

First, remove the cables for the spark plugs and coil. Then take the cap of the rotor (2 screws), and take the rotor out (simply pull it out). Push in the new rotor (there is a slot on the rotor so that it can only go in in one direction, the same that you took it out from). Screw on the new cap. Unscrew the old spark plugs; CHECK THEM for carbon, overheating, etc. Gap the new sparkplugs if needed (stock gapping is .35 if I remember correctly, but not sure 'cause I gap mine to .45). Put antiseize in the new plugs and put them on. Torque to spec (check manual for the number). Put boot protecting grease in the boots. Connect the new wires (check your manual for firing order; a 1 is marked on the cap for the first piston, and follow the order from there in the sequence stated in the manual).

That's pretty much it... In my 4-banger, it is a little more involved because I have to remove the AC compressor to get to the front 2 plugs, but it is still not that involved.

I understand what you mean about the manual; they sometimes are not too clear at all. This is why I have both the Chilton and Haynes, and I downloaded the Jeep Service Manual from another site, which is also a lot of help (except when each states a different toruqe setting, which DOES happen sometimes!).
