My 2000 tahoe wasnt starting, the old nipple part of the IAC would pop out and it wouldnt start. Well I replaced the IAC with a newer one, and its a screw style nipple. Well this morning it unscrewed it self out a bit and it wouldnt start. So I pulled the IAC tightened the nipple back down and now it starts.

My question is why this keeps happening and what can I do to fix this problem?

Thank you in advance.
