I wouldnt think it makes enough of a difference to require a tune.
It took about 5 hours, including getting used to all the tools and finding a speed that wouldnt load them up with aluminum.

We'll see how it works, i had a spare and time to kill so no biggie if i dont like it

I am still having issues with my Jeep. Replacing the IAC and CPS masked my problem for like a week or so and haven't solved my problem.

So I dropped my Jeep off at the shop today...... Yesterday was driving and my Jeep died once or twice during the day. Then I went out to dinner, on my way home my Jeep would be ~1200 RPMs then drop to ~200 RPMs all while driving but wouldn't die. I would put it in neutral, gave it a little gas and RPMs came back up. That happened last night about 6 times.

The last straw was turning onto my street, Jeep shut down mid turn and was dead. Put the tranny in neutral and tried starting the Jeep but nothing. Would crank and crank and crank but wouldn't fire up. Check gauges light was on, battery looked low, below the normal 14v. Let the Jeep sit for 2 or 3 mins and fired right back up. Was as to pull it home and when I parked it, Jeep died again.

So this morning I dropped it off at the shop....

So here's what I a. Thinking, and of course driving there this morning there were no problems, shop cannot get my Jeep to duplicate the problems...

Here's what I'm thinking..

1) Bad fuel pump?
2) Bad upstream O2 sensor?
3) Bad PCM

Please guys, any help would be greatly appreciated!!!!

When you get those tires, get all the same size this time lol. That way you won't have to "deflate one to match" and also run the risk of a blowout because it's old, bald, under inflated, and overheating.

Don't speak. It makes you look as dumb as you are.
We have a new fighter entering the ring with polka. I wonder who will win this time and how long it will go on. I just made popcorn and a bottle of beer. Let the fight begin. Ding ding ding.

C'mon dudes,lol. This is a cross section just like any city. Plenty of people, different conditions, different circumstances, different history, bad days,good days, *****ing boss, bonus day, unexpected bills, bigger refund, less refund, jeep runs good, jeep runs bad, mother in laws, lol, ect ect. One thing we all have in common is we like zj's, or at least want the things to roll. People that will use search, people that won't, people that ask newbie questions, which have been asked a billion times, people that won't listen when you try to help ect ect. People that ask a question and are told how stupid they are almost immediately....thats sad.

I enjoy this forum and look forward to reading it daily, not just for the info but for the varied personalities,and interaction with those personalities, all for a common cause. Not alot of that roaming around in the world today. I feel good when I can help and disappointed when I can't. If your having a bad day, thats cool, just try not to project it so much. I've had my share, and continue to have them, and for sure always will. But there are friends I've made here that I wouldn't hesitate to shoot the bull with if I felt the need. Its a mixing pot, you can't always have a clean spoon.

A hole saw and a vice is a good way to go. I used a brake honer and then sanded. Looks great and it's free! I didn't notice anything big but the throttle response was much better.
Awesome. I'll probably make that a project for this summer at some point then. I know I got better response when I put that TB on that I got from you. I don't know if it was because I cleaned it all up before I installed it, cleaned the IAC before I put it in there, or changed my plenum plate/gasket at the same time. It was probably a mix of all 3. We'll see if opening it up makes a bigger difference. Stock is a 50mm? How big do you think you could go before you'd require a tune or get adverse effects?

I've got a spare at home somewhere with a broken bolt in it that I couldn't get out. Maybe I'll mess with that one first if I can find it for practice. 5 hours isn't too bad. I could spread that out over a week and do it for about an hour a night. That's how I installed my e-fan so it didn't take up an entire day for me. I waited till my wife and daughter went to bed then went into the garage to work.

Hers did pretty much the same thing you described. Would idle fine but as soon as you got on the gas would bog down and damn near die. Could go a little ways until it got up to full operating temp the the **** would hit the fan...

Just a TB won't require a tune but I wouldn't go over 52 without having other mods.
If you don't have anything modded then 51 would be fine imo.

If I get around to it, I'll probably go to 51mm then. I'm not looking for huge gains or anything. If I can mod it for free and make it "better than it was," I'm game.

I am in need of a trans rebuild. They were not kidding when they said the 44RE was not enough for the 5.2. Fluid's perfect and it still occasionally slips the 2-3 shift with the throttle pinned.

I ran the same tires on my last truck and they did really well for an a/t. Been to barnwell down around Gilmer?

Give it a band adjustment. That can make a big difference on the 2 - 3 shift, although if it's been slipping for a while, it may just be worn out. Check the TV cable too. How many miles are on it?
