      They have i litlle valve system inside and when you get a good one you can shack it and its solid and the little valve inside keeps breaking off when that happens you can shake it and it rattles i'm just wondering if there is something else going on that keeps cousing this to happen or am i just being dumb and need to stop getting them from junk yards lol

          Are you sure cuz when my car first started doing this the first one i pulled off rattled and i replaced it with one that didnt rattle and it worked fine for about 3 month's then started idle spiking and acting all jerky wile driving it and i pulled it off and it was rattling like the last one. Then i thought just like you said "mabey they all rattle" so me and my bro stopped by the junk yard today and grabbed the only 2 iac's in the yard witch both rattle and neither worked.......but the one that didn't rattle worked.......sooooo i dont know are you sure?

                If you had said that more than one NEW ICV's have failed, I'd say that the ICM is bad. But with used parts all bets are off. Additionally intake leaks can look like a bad ICV. Have a shop run a smoke test and fix the leaks it reveals.

                    Intake leaks can result in no change in idle speed when the ICV is disconnected. Have a smoke test run.
