Im new to this forum and the jeep world. I bought my first YJ a little over a month ago. I believe I fell victim of a jeep that has sat for awhile. I'm having a rough idle issue and an issue with a really slow idle down. Ive change plugs, wires, distributor, cap and button. Ive also changed out the IAC, MAP, & TPS with little improvement. Any Ideas of what else to check / test before I take it to a mechanic? 2.4l motor
What do you mean by slow idle down? It takes longer than usual to come to idle?
If so, sounds like you have a vacuum leak somewhere. Check all hose connections for cracks along with hoses. Sometimes the hard plastic lines for 4wdr actuator motor will have small pin holes worn in them...if the leak is small enough it will give you a rough idle and the iac will try to compensate, thus the slow idle recovery.
Spray some carb cleaner around the intake and TB while running and see if the idle changes.

Its a 93
and by slow I mean when i started i, it revs to about 2100 rpms and takes about 15 seconds to idle down and if I take it out of gear to slow down I can be stopped for 10+ seconds before it goes to a normal idle.
Actually I'm having a few issues, I've got a "miss" when its cold from about 2500rpm til about 3200rpm. No power when trying to accelerate. Also having a hard time getting it into first and second gear when its cold..
