Idle Problems And Stalling
 

Hi, I have a 99 GT with 43k miles. sometimes when i start the car i hear a pop sound then it stalls and will not idle. After 5min of driving it seems to idle fine. This happends about once or twice a week I checked the codes and nothing comes up. Is there any common reason for this?
Thanks for the help.

Idle Air Control Sensor

about 100 bucks from Ford. Two bolts and a plug. Will not throw codes. My 98 was doing the same thing at one point. Dont forget to disconnect the battery while changing it out.

Hope this helps
