yea I was working on that thanks. Is there any larger pictures of this I really like it if it were 4X anyway thought I would post it for anyone who hasnt seen it. and well if youve seen it and don't like it oh-well :thwak:

The IAC that is on the 2.5 is a completely sealed unit not like th e4.0 that has a plunger style one.The only moving part is the idle stop that rests against the throttle body plate.

I need to re-phrase my last post. I previously had a high idle problem that would only go away when the IAC was tapped on pretty hard. I swapped that with another one but now the idle problem is all good but just when its started up it should idle up a little then slowly come down to a steady idle. I was wondering if anyone has any ideas , I was considering removing power to the truck and reconnecting the battery to see if it relearns th eidle position at a cold start up. :???:

Well the problem is fixed I found a IAC at a JY an swapped it after some adjusting it's working lIke it should.

I've got both Comanche emblems and one x from a Comanche X if your stll looking for these pm me and well see what we can work out.

I am almost sure the IACV is bad and really need one . I have a 1987 2.5 manual 2X4. The best way to contact me in 515-729-4582 and my name is Cory

I am having a problem with my 87 2.5 AX5 short bed two wheel drive MJ. I have been told that the sensors don't do anything untill it is up to opperating temp. so not sure swapping sensors would help. But If it is a vaccum leak why would it go away after it warms up and sometimes when I tap the throttle? Well any help would be great anyone out there have any suggestions? The problem is that it idles high after I start it sometimes it won't idle high till I have given it gas .

I wondered if the ISC was the problem I have messed with it a little and looks like it could be it. Ill have to check online and find one.

forgot to add that the truck sat idle for two days, then problem started on the third day when I started it and went to work. Ive used starting fluid, to see if there was a leak just in case but no leaks.

I have a 87 MJ with a 2.5L AX-5 trans and just the last two days Ive had a problem with the idle being to high. I have done nothing to the truck and it just started to idle high yesterday. I tried swaping the injector it is a throttle body injection system. Does anyone have an idea what could be causing this to happen. I was thinking it is the sensor on the rear of the throttle body but not sure I tried disconnecting it last night when I got home but didnt seem to change anything I did disconnect it while it was running. Any help would be great.

That might be my next thing to work on . I have just tested the ECU, MAP, and MAT sensor in my other 2.5 comanche and they all worked fine. I think it would be a good idea to drop the tank and check it all out.

Yes worked like a charm to put the six cyl coil. It has been running great

Awsome I'm getting rid of it and do it my way. I'm sure it may have served a purpose just would like to get rid of it.

Wondering about the support piece that goes directly above the frame rail and on top of the floor pan. I know they are two different vehicles but I will be redoing floor pans and would like to eliminate this part. I'm sure in extreme conditions this would help maybe but can I leave it out and mirror a Cherokees floorpan design. I did complete floors in my stepsons Cherokee and just wanted to see if this part that in most cases is rusted bad enough it can't really be that good at support or salvaged can be left out or if someone on here has done it this way . Just havent came across it that way yet
