2007 ST 4.6 with 50K miles misfires when driving after engine warms up. Engine temp at half way on gauge. No warning lights.
Thanks for your information, will get started on my project.Going to say it's the Plugs (there no wires). We have those awesome, two-piece plugs (the coils are on the plugs, no wires).
I'll give you the BAD news: I let my buddy, that I trust inherently. He charged me almost $800 to change the plugs and coils on my truck. The parts, themselves, were almost $600 of that $800 that he charged me. Going from the 2-piece plugs to single-piece plugs, that won't break-off in the head, will cost you probably $40/plug. Then, getting good, new caps for each plug, that's another 25-30/plug (for good ones) 65/80-per cylinder, yeah, it's expensive. But I did NOT want to mess with the single-piece plugs on this truck. I can't believe that it's not more spoken about than the big I'm griping about here!!!
Let us know what you figured out!Thanks for your information, will get started on my project.
