Yup. Get some seafoam deep creep or tb cleaner and spray the intake with 1/3 of the can with the car off. Wait 10mins and start the car. Look for where the white smoke is escaping. Listen too for vacuum leaks.
I would still tap the IAC lightly with the car on to see if there's a difference in the RPM's if you don't detect a vacuum leak.

First you need to troubleshoot and diagnose it. Check the connectors for the TPS, IAC and IAT to see if they are corroded. You should still see if there's a vacuum leak. Is the check engine light on? What code(s) is it throwing?

Sounds like a vacuum leak. IAC motor can not give it enough air to go 4500 RPMs. The air has to be coming from somewhere. Get a can of carb cleaner and start spraying around the intake with the car running. You will hear a change in RPMs when you hit the leak.

all the connectors are fine and the only code its throwing right now is the 24x? . but my uncle said that its a crank sensor but he says it wouldnt have anything to do with it goin ape **** the way it is. and as for vaccum leaks go. would a faulty injector ring let in enough air for this to happen? cause i got a new set today.

are you sure the throttle body butterfly's are closing all the way? check to make sure the throttle is not binding or sticking at partial throttle. it would take allot of air to get you to 4500rmps. if all your injectors are leaking air then it may but still takes allot of air. if i unplug my brake boost vacuum it wont go to 4500. thats a half inch hole.

update: fixed the problem. it was a mix of a few other vacuum leaks. the plastic T fitting that sits in the front of the intake was cracked so i need one of those. the fuel injectors werent set in all the way, and the throttle body gasket didnt cover up the back of the iac housing and allowed that to pull in air. but now i have one more question. my cars throwing a 24x code, what may this be?

Here's how to test the crankshaft position sensor to know if it's good or bad: http://troubleshootmyvehicle.com/mai...sor_test_1.php
