Have Ford Questions? Ask a Mechanic for Answers ASAP
Hi, welcome to Just Answer. I’m Ron and I’ll be helping youtoday.Before we get started though, Please understand that I don't knowyour skill level or tools you have to assist us. Also understand thatI can't see, smell, hear, or touch the vehicle either, so patience isappreciated. JA is a great Q/A site, but it does NOT replace arepair shop.My goal is to make you happy and get a great rating in return formy time. Sometimes I have to give you bad news that I know youdidn’t want to hear, so please don’t shoot the messenger.
At this point it's all guesswork. The only way you will know exactly what it is, is to do a tear down and an inspection. Anything is possible and it really doesn't matter what it is because it has to be torn down one way or the other. At least pull the front part of the motor down to expose the timing components.
So is an injector coil going bad and a flat spot on a fuel pump armature. This is where the testing is important for confirmation.
Thanks again and please remember to rate me 5 stars and keep this link in case you need me again later on.
Okay, My job was to direct you to the possibilities which I did.
