Just had a tuneup couple months back. Just got off the phone with a buddy and he mentioned could be in the idle circuit somewhere. I do a lot of 4x4ing and have three fuel filters (one before the electric fuel pump I just installed, two more just before the carb). The carb is a rebuilt I installed 1 year ago. Leaving in Ca sucks...I tend to tear down the carb tonight and blow/clean all the jets. I have some info from www.off-raod.com/jeep/tech/258bbd.htm. They have some other areas to look at, like the evaporation canister. The metering pins are working. I did a major vacuum hose replacement last year. I keep the jeep in tip-top shape. So when it does not run right I want to make it right.

Thaks for the comments

With all that in mind the first I would do is to take the fuel line off of the carb and put a low pressure gauge in at the carb location and check just what the pressure is. Why did you take the factory pump off of there? low or high pressure can cause idle problems..
