Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hello and welcome! My name is ***** ***** I can assist you with your question. Is the check engine on? Are there any codes in the computer? Are you looking for some possible causes or would you like me to walk you through this diagnoses?
Thanks for the reply and sorry for the delay! My experience has been that this is caused by bad secondary ignition components and or a bad mass air flow sensor provided the fuel pressure is good when this happens. Just be sure that the air intake snorkle from the MAF sensor to the throttle body is not cracked or ripped in anyway and that it is securely tightened on both sides.
Hello and sorry for the delay! YES, tempature is a huge factor in resistance. And when a sensor or an electrical part starts to go bad, it will go bad only under certain conditions or certain tempatures. For example, it might stop working when it gets hot but it may start working again once it cools off. I dont believe there is a fuel pressure test port on this engine but I could be wrong. You will have to double check. If not, then you will need to use a fuel pressure gauge and adapters to tap into the fuel line to check fuel pressure.
