My son and I both have '07 5.4's. Both trucks are both around 80,000 miles.
Both trucks have a hellofa shake rattle and roll. Mine when hot and loaded like up on an incline, pulling a light duty trailer, etc. His, sometimes cold and at idle, but most of the time when hot.

We both had the plugs changed and I had coils changed on mine. Still not like it was prior to the trouble.

Can anyone give me some insight as to what is going on before I simply put myself at the mercy of a ford dealer?

Thanks in advance for your comments.

 

Is feels like a herky jerky transmission issue, advisors say not so.
is there a common problem that might be causing this?
HELP!!
