Ooookay so my tj has this really strange issue that I have spent much time and money trying to fix and it just won't quit every now and then when I'm slowing down (usaully when stopping) it will begin to shake and I can see the rpm dropping down to abnormal levels (like 100 rpm and below) like trys to stall then it just resumes running I have had the transmission rebuilt already and have taken it to the shop that rebuilt it 4 times now there are no codes when I scan it and I am running out of ideas if anyone has any insight at all I would appreciate it greatly (edit it's a 32RH automatic I'm not an idiot guys I swear)

Have you cleaned the idle control valve? Mine was auto was doing something similar until I cleaned the idle control.
Is that same as the iac? In the throttle body because if so yeah I cleaned that off with brake clean and a micro fiber cloth now it does have throttle body spacer (stupid mod I know) do you think that could mess with the iac?

Yes the IAC, don't Know about the spacer though, maybe @Chris or @mrblaine or some of the other gurus could answer that.

Its an automatic!!!! 😂😂😂
I didn't see you're edit until I'd already responded, oops!

I cleaned it about 3 months ago do you think it could need cleaning again? Or maybe it's broken
Doubtful. In that case I'd rule the IAC out. Have you checked for vacuum leaks? Sometimes this requires a smoke test as they are often times too hard to see with the naked eye, or in places you can't see to begin with.

Yeah the only one I've found was for my climate control and cruise control I got it fixed but do you have any tips on checking for more leaks?

Yea, I noticed

Love my auto, but I am about to turn 62 and have had both knees replaced.😖
I don't really mind the auto it's just i prefer a manual all day over an auto I feel your pain with the knee trouble though I'm only 21 I'm looking at a replacement for my right knee in near future all that time skateboarding and crashing have caught up to me fast!
