What is this dangling doodad????

I was underneath my Jeep and saw this hanging in the space between the intake manifold runners. I looks like it could, maybe should, screw to the IAC, which has a plate. 93 with 2.5 that PO installed a 4.0 TB and spacer. The number on the back seems to be 08025A3002.

This is the first IAC delete i have ever seen. I guess Bubba did not like his jeep to idle without his foot on the throttle.

I have had the Jeep for 2.5 years and it idles fine. 800ish rpms. I guess I will attach it and see what happens. Worse thing can be is to unattach and reattach the homemade delete.

Since, the IAC is non-functional, I am assuming PO manually adjusted the idle. What might the negative issues be?

Your Jeep won't give itself throttle when needed such as idling up a hill, also it won't self adjust to extreme changes of temperature or changes in altitude..

Otherwise probably no negatives

Would this condition cause the engine to run rich?

looks like a hose clamp has been put on the iacv. Depending on open or closed would that cause the ecm to dump more or less fuel in causing a rich or lean condition?

I am a leaner towards correct, so I would get it back to working. I would buy a new iacv though because that one may be, prolly is, bad.

Is it running good? Leave it alone. Won't cause to run rich.

To recap what I've read here, elsewhere and after talking to a mechanic friend. The IAC is not a mission critical part and since it is idling correctly as is, leave it alone. There may be some bad idling at altitude or in cold weather. If I have misunderstood, please let me know.

It is a cheap part. I would buy a new one and put it back together as it should be. It is all but maybe a 10 min job.

If I replace it, are there any brands to avoid? Or is whatever NAPA or O'Reilly's has okay?

That depends on who you ask. I would just buy whatever brand and call it good.

Got back from the mountains and replaced the IAC today and this is what I found lurking behind the homemade plate.

Southern engineering at its best.
