Changed the IAC and still idles low. Sometimes will not stay running when you start it other times runs fine. Had timing belt replaced about six months ago. Was doing the same thing before I changed timing belt. Been checked for vacuum leaks and mine are found. Put on a computer and no codes were found. Any suggestions or help would be greatly appreciated.

Hi AMANDA,

It sounds like you have a mass air flow problem, what happens is the element in the sensor becomes dirty so computer cannot get a good reading, lets try cleaning the sensor first here is a guide that will help you get the problem fixed.
