1987 Jeep Wrangler NOOB

Hello all,

I am a first time Jeep owner and purchased a 1987 Jeep Wrangler with a I6 4.2L. I was having issues with it idling rough and stalling when stopping at lights. I have pulled the carb and was informed that the throttle body could be an issue as well.

I could take it to someone to fix as I am not a mechanic; however, I would like to fix the dang thing myself. I bought this as a hunting vehicle for my newly purchased ranch. It doesn't have to be perfect, but I would like it to be dependable and street worthy.

Could someone lead me in the right direction as to the fix for this vehicle. A couple of people suggested getting it running, selling it and purchasing another model Jeep. If this is the case cool, I'll do it. These suggestions came from persons that owned a Jeep dealership, so I am looking for unbiased suggestions.

I have yet to figure out where to find the throttle body and am not finished with the carb rebuild.

Thanks all!

M.A.

First, I would ask you to fill out your profile
Next, What kind of carb are you dealing with? the stock one?

The 87 4.2 doesn't have a throttle body, it should have a carb. The stock cater carbs are junk and are noted to be problematic. One of the best replacement carbs is a ford motorcraft. There's a guy on ebay that sells them ready to bolt onto a jeep and totally rebuilt with great customer service. I have a holley 470 4 barrel on my 87 that works awesome, but I have alot of hipo parts as well to handle the 4 barrel. Ditching the carter is a good place to start if thats what you have on there.

and the one you have will work great for what you want it for. mine is a daily and works fine but i put another carb on it too, also a holley but a two barrel variant from a 68 dodge. works great now

I don't feel like working on anything at this time so i sold my yj.

Hah, they just want to sell you a car that looks like a Jeep.

Anyway, get the carb rebuild finished up and see if it helps. If not you may just need a tuneup. All good things to do on a new to you Jeep anyway. Learning to do all your own work is kind of a right of passage with an older Jeep, they are too expensive to own if you have to use a mechanic for everything, IMHO. Plus its a good learning experience, I like to be as self reliant as possible.

Back on point, how does it run other than the idle issue?
