i have a 2003 mustang gt its got a cold air intake and wen it idles it idles fine then it drops real low then idles fine then drops ext (keeps doin it)
it occasionally dies but almost never it jus keeps doing it no check engine light either
Check your throttle body, make sure it is clean, check for umetered air leaks around the cold air system. ISC could also be stuck.
Idle Speed Control
anything else you recommend
You might take it by a major parts store and have the codes pulled, there might be a code that can help with further diagnosis, there is also a throttle position sensor that can also go haywire.
thank you very much
