Do you have the V6 or V8 engine? Does it seem to misfire at idle too? Thanks.

V6 and yes
Customer reply replied 8 months ago
I just checked the coil and all are arching
Ford Mechanic: Dan, Technician replied 8 months ago

Considering what has been replaced the only things left are pretty much engine mechanical such as valve, camshaft, rocket arm, ect or injector. I would start by doing a compression test to verify compression is similar to the other cylinders and if not next step is to do a leakdown test to see where compression is being lost. If compression is good then I would go ahead and replace injector. Let me know if you have more questions or if there is anything else I can do to help. Thanks.

AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.
