Was going to get the converter replaced today...but I cannot keep the Jeep running!! I dont know what has happened. Im stranded until I can get past this issue. When I first start it, it idles well...after a bit, it acts like it wants to die. If i lightly pump the pedal I can keep it going. I am at a loss, does anyone have any ideas?
I can PM my phone number if someone wants to call me with ideas...
Ill check the vacuum lines very closely. Is there a simplified vac diagram that shows how things should be hooked up WITHOUT the emissions acc? lll double check the lines and see if I missed something...
Did you change something before it stopped running? If not, just get it running, and then use some brake clean or the like and spray around vacuum line hookups, and listen for the idle change.
I wanted to simplify the hose situation under the hood...so much of it. I wanted to have it so that the brake booster, distributor and the heater/ vacuum line for the transfer case and nothing else. I think I goofed something up. Ill have to go back and re connect everything as per the vacuum diagram. Should not be too hard I did not remove any canisters or the like, just hoses.
I have seen the 360's without all the emissions stuff and they look very clean. All the emissions on mine is either shot or gone with only a couple of canisters left and a crap ton of lines.
Soon as it warms up some Ill put it back the way its supposed to be then do it right later...
What you might do is plug all of the lines at the carb and manifold tree, except the PCV, and see if that 'fixes' your problem. Then you can methodically add each circuit back into place and check as each new connection is made.

This, I would bet that you left a vacuum port open somewhere. Find it and cap it. Try again. Usually that little sucker on the back passenger side of the carb. it's hard to see.

That behavior suggests either excessive air (vacuum leak) or inadequate fuel. Pop the lid off the carburetor and see if there's any dirt or crud in the float bowl. Clean it out. With the engine running, try opening the idler mixture screws a few turns one at a time and then back to their original position. That may allow any dirt that has become lodged in the idle circuit to dislodge itself and restore correct fuel flow through the idle circuit.

Yep, what they said. Dont put all the vacuum stuff back on but find all the open ports and plug them. My vehicles only use the PVC, distributor, brake boster and Power valve lines. Good luck
I now have only the PCV valve, Master cylinder, and the distributor...hooked up to the vacuum. I will double check to make sure my 4WD is getting it too. Question is, should I adjust the timing now?
I would suggest making no changes until after you have verified that the float bowl and idle circuits are clean.
Many a good-running vehicle has been hobbled by people removing components that weren't causing a problem. Before you introduce changes, make sure everything is working as designed.

Sounds like time to cut your losses and hire a mechanic.

Get a cheap (or expensive) fuel pressure gauge, connected as close to the carb as you can. I have one with the gauge in the cab, absolutely love it. This won't fix your problem but will verify if it is a fuel delivery issue.
