It keeps high revving up and down after car is on 2006 hyundia accent
Check for a vacuum leak, and clean throttle body and Idle control valve of carbon. See if that helps.
put a diagnostic scanner on that...they are around 15 dollars each from Amazon~ the diagnostic port is within' three feet of the ignition switch~
Did the cleaning and replaced the actuator assy-idle speed problem still going and I'm about to hook it up to the PC now
Tom is right...that condition sounds like a vacuum leak~
RTV black was my staple for sealing (make-A-gasket) material....a few beads of this where it's whistlin' will cure this~
Checked the hoses all is good but I once I disconnect the idel air control problem stops
You know what to do then~
