It could be that sure. Im just saying with my jeep that's how it started. when i got it it was all factory. And then it started to have problems with starting. It would crank forever and then kind of backfire and then when it would actually start but it wouldn't keep running at idle. So at first i did a tune up. Just Plug wires and cap and rotor and plugs and air filter and fuel and then it just got worse from there. It wouldn't start at all. I did replace my fuel pump and after that it would start better but still it wouldn't keep running at idle. I didn't have a clue on how to tune my carter carb and have read alot about how crappy they are so i replaced mine with a Motorcraft 2100 and then it would start easy but at high rpms it would misfire and lose power. So i did nutter bypass and didn't help much so i replaced everything. The whole distributor and ripped out all the wireing that is to the ignition module and did that all in one distributor and now she is perfect. The jeep is free of any computer controlled setup. It runs like a CJ before computers. And I think i have more fingers and toes then this jeep has in wireing now. Deffinitly in vacum lines.

I hope you get yours figured out and hopefully your jeep won't keep giving you problems but they all are getting old and hard to keep running.

Is it a 4.2 carb engine?

Well i have a 1990 and it's the same kind of jeep but with the 6cylender 4.2 carb. Is yours? I will assume so cause they are always giving problems these days. The only thing i can tell you is if you want to enjoy your 4.2 6cylender carbed engine then you need to do the easiest mods to improve your jeep and forget trying to keep it factory specs.

#1 Get rid of your carter carb and switch to a Motor Craft 2100
#2 Do nutter bypass. (Research that. Its easy to do and find the info)
#3 Rip out all of your vacum lines after all is running with this setup and then only use Vacum for 4wd and PCV, Brake booster and Distributor advance timing. Now if your state is really picky about emmisions then keep your EGR valve and that will be another vacum hook up. (I didn't keep mine)

Now if you still are having some trouble then look into replacing the Ignition module under antifreeze jug or distributor and not just the cap but the whole thing.

Now with my jeep i didn't keep anything. I replaced everything. Not just spark plug wires and plugs but the distributor and i got one that is all in one and that means everything came out and now my ignition coil and module is on the distributor. That's at Jeep Esstientials Look up DUI distributor. If you do the DUI distributor then the nutter bypass isn't something you need to do and if you decide to do that before you even do the bypass then that will save you time.

My jeep is a real jeep after replacing everything and i don't have any problems. These are so old and it's time to just replace all and have fun.

The black stuff coming out of tail pipe can just be Carbon from a clogged cat which can be your problem and i would check that the first thing before everything else. But like i said to enjoy your jeep do all that stuff.
