Ford techs replace pvc hose clean fuel injectors and clean throttle body perform complete intake and fuel injector service. Replaced idle air control valve assy. Replaced upper and lower intake gaskets. Replaced left and right pvc vacuum hoses. Engine light is still on and car is still idled high.
Hi There, It sounds like the throttle body has not been put through a "relearning" process. When the throttle body is replaced, this often times requires that the car go through a process which helps to re-calibrate the throttle body. Try doing the following which should bring the idle back down to a normal operating level:
1) Start the engine and let it idle in park for 3 minutes. During that period the idle may be higher idle than normal. 2) After 3 minutes, turn the engine off and leave it off for 60- seconds. 3) Start the engine again and let it idle in park for 3 minutes one more time. During these run periods you may see a check engine light. Scan for codes and if you get throttle body related codes, clear them. 4) If the idle speed is still off, drive the vehicle at speeds above 45-mph and operate several acceleration and deceleration cycles. Then repeat step #3 one last time.
This should bring your idle back down to normal. Should you need further help with this, please reach out to us here at YourMechanic as we are always here to help.
