I was changing my spark plug wires and I think I messed up the pattern. Yeah I'm a loser. It's a 98 Tj 4.0. Please help.

/wwwthreads_images/icons/smile.gif Yars.....I just checked with my crew chief moonguy/wwwthreads_images/icons/wink.gif and he says that you are NOT a loser. (1) you have a Jeep; and (2) you have brains enough to go where there is help available. FIRST, notice that there is a big , fat, number 1 on the distributor cap....usually at about five o'clock. THEN...remember that the engine fires 1-5-3-6-2-4 and then back to 1-5-3-6-2-4 AND...the number 1 cylinder is in front, and 6 is in the rear. SO...connect the front cylinder to the terminal on the cap marked 1, and then in a CLOCKWISE direction, hook 5 next, then 3, then 6, then 2, and then 4....PRESTO! Jeep is OK again!!!! My moonguys are asking about beer./wwwthreads_images/icons/crazy.gif they want you to send a six pack./wwwthreads_images/icons/crazy.gif

I never believe any statistics unless my moonguys /wwwthreads_images/icons/crazy.gif/wwwthreads_images/icons/wink.gif made 'em up themselves.

You are not a looser, you admitted your lack of knowledge, instead of swearing you know everything about all off road vehicles, and saying aliens (or the CIA) switched everything around when you weren't looking!
(At least you didn't claim that Corvettes never came with leaf springs...)
This is a minor screw up, and it happens every day...
At least you are trying to pull some maintenance on your vehicle, instead of ignoring it till it quits...

CJ Dave is correct, but some of the replacement distributor caps don't have the #1 marked on them.
If you are not sure about #1, do the cork in the #1 (very front) spark plug hole, and turn the engine over until it pops out. (Don't hammer it in there!)
When the cork pops, turn the balancer over until the mark lines up with the timing scale on the front cover...
Take the distributor cap off, and where the rotor is pointing is #1.

Use a magic marker and write the firing order CLOCKWISE on the cap, 1-5-3-6-2-4.
You should be able to find this firing order cast into the intake manifold somewhere on top.
(Trivia time, all I-6 engines, regardless of manufacturer, have the same firing order)
Like CJ Dave said, the cylinders are numbered from front to rear, 1-2-3-4-5-6.
Now, just play connect the numbers.
Now, do you know what time it is? ............ Beer-Thirty! You're done, pop a top and hang...
Turn the key, and rub your new found knowledge in the face of the guys that you hang around with.
(You may be able to make some beer money doing their Jeeps!)

Don't forget to get a good quality cap with BRASS terminals. You are just wasting time using a cap with aluminum terminals.

Good luck dude, and if you need help again, just ask.

When a fool and a wise man argue, Onlookers can't tell the difference...

Just remember, in the future, do like I always do when changing plugs or wires, one at a time. It will definitely save you time and a headache later. BTW, I think everyone has done what you did when they first started messing with cars.

Get active or get locked out, the choice is yours.
