2000 XJ a couple questions
 

Ok so my 2000 XJ with 182,000 miles has a couple issues, 1) It has a random misfire Cylinders 1 and 3. the plugs arent too old maybe 20,000 miles on them. I am thinking the Coil Pack (dosent have distributor) and some new plugs will do the trick. 2) My blinkers like to frezze up every now and then the switch is maybe 2 months old, I bought it new from Jeep $80.

Now I am going to be lifting the XJ 3" with a Rusty's 3" new leaf pack kit, steering stabilizer, lower control arms, transfer case lowering kit, and quick disconnets. All the stuff will be Rusty's. I know I will need a tracbar but for now my jeep will be mostly Daily Driver Duty. Plus the stocker was replaced like 2 months ago. I plan on Running no bigger than 31" tires for now. And in the future I plan to add 1-Ton steering, Aussie Lockers, New track bar, custom rear bumper, flowmaster or dynomax exhaust and some other stuff. Is there anything else I should worry about?

Not too terribly familiar with the coil set up on the distributorless XJ's, but I believe there's only three coil packs, each one going to two spark plugs. You could try swapping coil packs to see if the cylinder misfire code follows.

For the blinkers freezing, that sounds like the turn signal solenoid (the thing that "clicks" when the signal is blinking). I had that same problem with mine. It's really easy to replace (located behind the kick pannel under the steering wheel) and will only cost a few bucks to get a new one from your local auto parts store.
