How long has it been doing this?
Only for the latest tank of gas?

Does it only do it on a cold engine?
Auto choke/mixture?

Does it idle smooth?
If so, at what rpm?

How long has it been since you had new plugs/wires?
When you look under the hood at night with all the lights out, do you see sparks jumping from leaking wires?

Are u getting a service engine soon light? Mine was doing much the same and kept giving misfire on number one cylinder. Changed plug, wires and still same so I put in a can of sea foam into the tank... Half a tank later all is good(: no lights no bucking like a newish jeep(:

Welcome aboard! When was the last time your jeep had a tune-up? Does it do it worse on cold days? wet days?

Welcome. Sounds like you need plugs and wires for starters.
