    Default 2004 mustang gt idle problems

    Hello everyone, I need help. I have a stock 2004 mustang GT. After driving the car for about 10-15 miles it starts dying when I come to a stop or when I push in the clutch. I can keep it running if I stay on the throttle. I've changed out the PCV value and the vacuum hoses leading to that and the intake. I've ran a diagnostic test on it and it reads like nothing is wrong with it. Any ideas would be greatly appreciated.

    If you replace any parts go with Ford parts. I wasted time buying parts from rock auto and then the car threw new codes.

    I have had some issues like that in the past when the solenoid valve in the back of the intake was bad that controls the vacuum for the EGR. I cannot remember the exact name of it right now...maybe someone will chime in with the correct name

    +1 on the ford oem parts. The others are a waste of time and money.

    That's the IAC

    The iac is on the front of the throttle body plenum.

    This is a vacuum solenoid valve on the back side over by the egr valve
