Where is the idle air control motor located?

round housing with a 4 wire connector on the throttle body.

why are you replacing it??

roy im replacing it because my car turns off on idle. it always turns back on for like 3 seconds then it just turns off. i happen to believe maybe its the idle air control motor.. any suggestions??

wrenchtech thanks you so much that was very helpful.

i would check for vacuum leaks at the base as the base gasket is a common failure for this issue.

make sure the egr valve is not stuck open causing a massive vacuum leak.

and lastly, it could be the valve but can be tested with a scan tool to manually operate it.

*UPDATE* I already changed the idle air control valve (IAC) and the EGR valve and also the throttle position sensor along with the pcv valve. I put all these parts new and it still does the same thing. the car always turns on but turns off after 3 seconds. I dont know if its either a leak or something causing it to choke. It also drains the battery i always have to jump start it to turn it on every time. please help..

Have you tested the fuel pressure?

No I havent not yet

That probably should have been the first thing you did.
It has to be 9-13PSI

so i checked the fuel pressure and its good i even changed the fuel filter. what i did notice was that the car only stays on when i disconnect the hose that runs from the back of the throttle to the map sensor, once i connect it back to the throttle the car shakes and it turns off. So I'm thinking maybe i have a bad MAP sensor, so i go and replace it brand new and it still does the same thing. It only stays on when i disconnect the hose from the throttle that goes to the MAP sensor. What could this be? and after i replaced the MAP sensor the check engine light went off. so i dont know what to do anymore? any suggestions?

Try unplugging the the electrical plug for the MAP sensor and see if it will run any better.

ok ill try that now.. what will that do or what?

That will force the computer to default to a predetermine setting.

i did that and the car turned off. so what i ended up doing was checking the check engine light manually (since the light came on again) and it gives me code #34 map sensor signal out of range, low... so what do i do now?

Clear the code and start over. You triggered that code when you unplugged it. Try starting it after it is unplugged.

so i ended up replacing the ECM and its not giving me the map sensor code anymore. but it is giving me code 22 which is tps sensor low signal. the sensor is brand new why would this be happening? i tested the sensor out and it is getting enough voltage and ground from the ECM but its not sending its signal back to ECM. what can i do?
