Hey does anyone know exactly where the high altitude jumper is on a 4.2 YJ

Hey how hot does your YJ run mine sits exactly between 100 and 210, and im a little cold in the snow. If that is the right temp any ideas on getting a little more heat out?

Ok so I just rebuilt my POS Carter 2 bbl and went to hook up vaccuum again and have a port on the back of my carb right below the stepper motor that is open and I cant figure out what goes there? Now I also cant get the thing to idle right. Ive read a bunch of stuff online and have figured a...

Hey so just re ran all most of my vaccuum lines in my 88yj 4.2L with the 2 BBL Carter...i know a pos....anyways when the brake booster connects to the intake manifold there is another vacuum port but I dont have any idea where it is supposed to run. According to the diagram I have in my Chilton...

Hey does anyone know where the MCU is located or more specifically where the high altitude jumper is. The chilton's manual says the jumper should be located next to the MCU but I cant seem to find out where that is. Also, anyone know of any good things to jumper it with? Thanks

Hey so was driving home and when I got out I noticed steam rolling out the hood. When i opened up the hood I saw coolant leaking out of the bottom of the intake, but not at the seal, it seemed more like a plug had backed out of the manifold and was letting all of my coolant out. Anyone have...

Hey so I am looking to get a little more clearance on my YJ and was thinking about doing a body lift. It looks fairly simple and cheap as far as lifts go. I was only planning on doing a 1" lift. I read a walk through for a TJ, and everything seemed easy enough to do as long as you have...

Ok so I am thinking about changing the jet sizing because most of the driving I do is going to and driving around Tahoe. Right now everything is calibrated for sea level and I was wondering A) is it even worth adjusting the carb B) if so should I worry about jet size

Hey so I am putting my 4.2 st 6 back together after taking the carb off and have two connectors one is a two pin red and yellow right above the carb along with a single pin connector with a purple wire running to it also above the carb. Cant really find any open connectors so I am a little...

4.2 liter St 6 YJ photos Hey anyone have any photos of said engine compartment, I had to replace my manifold gaskets and did it a little too hastily and forgot to take pictures and now am trying to remember where all the hoses and tubes go...also I would follow the wiring diagram except that...

Hey anyone put some locking hubs on the front of a YJ? I see warn has some conversion kit but cant figure out wether you need the kit to put these things on or wether you can just slap on some locking hubs.

Hey anyone know if there is a roof rack that completely clamps to the hard top and doesn't require and funky brackets, etc. that mount to the body.

Hey so i know that they make a 21 spline AX-15, which I am assuming is the 88-91 rebuilt AX-15c (found on tellico4x4.com). My BA10/5 is shot as I said on previous post. instead of rebuilding the POS BA10/5 I want to swap in the AX-15 and can get the trans for 1100 but wanna know if i will need...

Hey so I was driving home tonight and my trans got stuck in gear but I could still move the shifter around but not into the gear it was in. The clutch still worked but like I said I couldnt get it in gear or get it back out of gear. Hey maybe Ill be getting that trans a little sooner than I...

Hey so I am looking into getting a locker...kinda like the whole simplicity of an ox locker but am also intrigued by Detroit's and aussie's Just thought I would get some opinions

Ok so I need to put in a new exhaust manifold gasket, which looks like a bundle of joy to do: draining the radiator, pulling air intake, carb, intake manifold, exhaust manifold. So my question is would it be worth it to re do the entire vacuum system that deals with the carb when I am doing...

Hey not really sure what I am talking about, but I noticed that I have two vacuum things one green one yellow mounted to the tub at the back of the engine compartment. The green one has had the vacuum tube mount thing break off and I think it is affecting my EGR because that is where the tube...
