Have Ford Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.I would start first with cleaning the IAC (idle air control valve) located on the throttle body as well as making sure the EGR valve does not have vacuum to it with the engine at idle. If after doing both and the problem remains then the system is going to need to be scanned and the fault code and or codes retrieved to determine what is causing the problem you are having. Ti=his will require a scan code that can access the OBD I system.
