Hello all...I just wanted some insight where to start exactly with a bouncy idle...Have '97 TJ Sahara AT...the tach slightly fluctuates up and down at idle...not a major problem cause I have no stalling or performance issues, but just something that bugs me... Any advise would be greatly appreciated...Thanks.

how much does it fluctuate? when i am running with my lights on, my fan on, and i'm just sitting there, mine will change a couple hundred rpm's, but it's nothing that i'm worried about or that bothers me, so i just deal with it.

It only fluctuates a few hundred as well, but the tach needle is noticeably bouncing...I only ask b/c it used to never do this. The only issue I know of I have is an exhaust leak post cat...could this be the culprit? I have cleaned out my TB already, but I was unsure of maybe the IAC or TPS could be causing this?
