Hey everyone, My jeep has been idling rough, RPM's jumping during idle, and just cutting off when slowing down or idling so I searched and came up with cleaning the IAC since i got a new battery and everything. I took it out, cleaned it, and put it back in. When I went to start it up it started and immediately shut off. The only way I can get it to stay on is to have my foot on the gas. I cleaned it with carbon cleaner, and when i did I did not know about twisting the IAC, and I did, and the springs were showing, but it did not look broken. After I took it out the second time to see what was going on with the IAC it looked like it did the first time I took it out. Could this problem be caused by me cleaning the IAC or breaking it??? Sucks i'm gonna have to miss work tomorrow.
When ever you have the battery out the sensors need to relearn everything including idle points, start her up and keep your foot down at around 1100-1300rpm for a minute or two and then you should be good to go

You can test an IAC valve.

Yep, thats it, sorry I was missing the 0 at the beginning, and how would I go about that? I played with the plunger a bit reading around on the forum and pushed it all the way in, so I don't know if I screwed it up or not.
A little update, after going to autozone to get a new IAC me and my co worker came back to install it. I was telling him about how far it was, and somehow he got it screwed back in. We put the old one back in and started it up, it ran but idled at about 2000RPM, which sounds like the symptoms of a new one. We took it for a drive and tried to maintain 40mph but it's rush hour so we were really doing 55-60. It still did it when we parked it. My question is is there anything else I can do so the computer can reset it? if not i'll just try again when i'm on my way to work again tonight.
