rough idle then dies
 
so, when i start my jeep up and start to drive, it starts to idle really rough when its cold. like to the point where it cuts off. it only does this when its cold or its raining. i live near the coast but i recently moved to the Appalachian mountains. does my jeep have a altitude problem or do carburetors just not like cold wet conditions. i have use seafoam cuz i thought that the jets might be clogged but like i said before, once the engine gets warm it run fine. any tips on stuff i should do, other than let it run for 10 min. before i drive(i cant afford to waste gas)?

Check and adjust your automatic choke.

Bought my Jeep from a gal that moved to the Denver area from Iowa, that had serious problems with it running correctly. Timing and air/fuel mixture was off. I corrected it and have had no problems since.

Mine acts like that in the damp and cold when my distributor cap and rotor are old and grumpy in the weather. Maybe time for a new set?

Our car was just doing this and I had a look and had sparks flying out of three wire boots on the coil packs. It is worth a check, I test for leaky wires by spray misting them with water in the dark while it's running. I didn't even need the dark or mist on the car, they were big sparks.

Mine was doing the exact same thing, maybe not quiet so rough but I am a perfectionist. I replaced my 6 year old Plug Wires and it actually smoothed it right out...
