my 02 sport trac idles rough and the idle scensor has been changed by ford but it still isn't running like it should what can i do?,without bringing the truck to ford.
Replace or clean the IAC. It is a common cause of poor idle. If that dosent fix it then it may be the MAF is dirty. The IAC can be cleaned and often improve the overall idle and save a little $ insted of buying a new one.
