high idle problems among others

Just bought my first jeep in october. black 88 jeep wrangler 2.5 L 4 cyl 5 speed. no real problems except ive had to replace the starter twice since. just moved to florida from ny and couldnt wait to get the soft top off but... having trouble with a high idle, idles round 1500 to 1800 rpms in neutral but goes down when shifting through the gears. cannot figure out the problem. ordered a crown tune up kit and awaiting its delivery. hoping that will fix the problem. also having difficulty shifting thru 1st, 2nd and 3rd gears. clutch was nice and worn in but now feels tight when engaging gears. probably low on transmission fluid but cannot get to that damn bolt on the tranny. if anyone has any advice or tips please help me.

Replacing the IAC is pretty easy and cheap. My 89yj 2.5 had an idle problem the same as yours and the iac had a short. Really without a mechanic this is just throwing parts at it.....

thanks for your help looking for the part but no one seems to carry it... where did you find yours? also one more stupid question, tryin to flush out my tranny but cant get to the fill plug do you need to drop the skid plate to get to it. that would seem like too much work.
