The idle is computer controlled. It takes a reading from the crankshaft position sensor as well as the camshaft position sensor along with basic information from other sensors, processes it and sends a pulse signal to the intake air control valve (IAC). The IAC valve is positioned to allow air to bypass the throttle plate and control the idle. Once the throttle is opened the IAC is commanded on 100% until the throttle is closed. In short, a scan of the pids needs to be done to determine whether the processor is commanding the IAC on properly or if the IAC just isn't responding properly.

A scan for codes can be done but many times an IAC won't throw a code so the sensor pids really need to be performed to determine the root cause.Good luck.

remove and clean the idle sensor valve. pull out and clean the PCV valve (on top of the valve cover).blow out (from the inside) the air filter. do not apply gas until after your vehicle starts.

Yukon was running and all the sudden died started up service engine light came on idles super low in gear and dies unless you put foot on gas and brake if stopped


easiest & probably cheapest way is to run into an autozone or Pep Boys & get them to scan fro codes for free & go from there. Get back to us with code(s) unless it's a simple one & part is right there at store to fix it.
