Stalling

I have an '87 YJ with a 258 I6, TR upgrade, MSD 6A, recently rebuilt carter and K&N filter. The MSD was hooked up so that the computer is out of the picture and it is connected directly to the distributor and the coil. I recently had the mechanic adjust the timing and it was running really smoothly. Quicker to warm up and have not had a problem starting it since the upgrades and idling was great. I recently noticed that after doing a litlle hihway driving, and then switching back to street driving, the idle becomes very shaky. Also, after I started it tonight, i gave it a bit of gas after about 3 or 4 minutes to bring it out of high idle and it went down a bit to about 1500 RPMs. It was not idling so well and when I gave it gas it almost sounded like it was congested. It made a funny sound, kind of like it was clearing something out and then made a smooth sound(while on the gas). When i released the gas, the voltage dropped and the car stalled. This is the first time i had a stalling problem since the upgrades and since the timing was adjusted. From the symptoms described, does anyone have an idea of what might be the cause. I have a Weber in the garage that I am going to rebuild but was hoping to wait till the spring till it gets a bit warmer to do the install. Someone I spoke to said it may be a vaccum problem, but how can I tell that for sure and if it is that, how do I fix it? If anyone has any suggestions, please let me know. Thanks in advance.

Re: Stalling

I too have an 87 YJ with the Carter and TR. I know that funny sound that you're talking about, I get that sometimes when its cold and I go around a corner at low RPMs in third, then I give it gas to get back up to speed it will hesitate for a second then make that kinda (farting?) backfiring noise, then it will be fine. Sounds like its coming from the carb. I too have a mysterious stalling problem that only rears its head (seemingly) when there is moisture in the air. It just plain won't idle. If I am driving it will feel almost normal (hesitates a little bit) but as soon as I put the clutch in it just dies, no sputter. But then its fine after 5-7 stalls and startups. Sorry I don't have an answer but at least you know I'm having the same symptoms with the Carter.

Re: Stalling

What your saying makes sense considering it was really foggy and wet in New York last night and yesterday. But I still have that bad idle after highway driving. Can't wait for it to get warm so I can put the Weber on. Should make the jeep more consistent, I hope. Thanks.

Re: Stalling

Even though you just rebuilt that Carter, check the idle tubes, it take so little to plug them. Its very easy to check or repair: remove choke plate and shaft, unscrew the venturi cluster (the part in the middle of the throttle bore) and look at the skinny tubes that point downward. It often takes a strong solvent and stiff wire (I would normally not probe a good carb with wire) to clear the tubes. Reassemble and you may have to readjust your base idle to compensate for the clear tubes. It may just do the trick, and if its not the problem, you've only spent ten minutes and eliminated a possibility. Good luck

Re: Stalling

When I first got my Jeep it wouldn't idle for anything for a couple of weeks, ran like absolute crap. I replaced the sol-vac and had my mechanic adjust it a few times and still nothing.

I then cleaned out the idle tubes like tlendt1 said, and the difference was night and day! BY FAR the one procedure all Carter owners should complete on a semi-annual basis, only takes 20 minutes once you know what you're doing.
