I just purchased an F-150 with the 5.4 Engine and have noticed it idles a little rough. I can see the passengers seat vibrate a little when I'm idling.
Also the radio has a little static on stations that I've never had problems with before in other vehicles.
Anyone ever experienced this before?
Could these problems be related?

Thanks for your advice.

If something's messed up with the ignition systems (spark plugs, wires, etc) it can often cause roughness and introduce noise into your radio.

 

take it back to the dealer. Make them fix it under warranty.

 

I'd take it back to the dealer and have them check it out under warranty. My 5.4 runs extremely smooth to the point where I would forget it was running if I didn't have an aftermarket exhaust.

 

Thanks for the dialog. This is my first V-8 and i didn't know what to expect. This helps me a lot. I'm bringing it back to the dealership after Christmas.
