07' 5.4 Rattle and Burp

[Aurora]

Gents,

After backing up my trailer again this evening I got what has been a recurring issue. Every time I have to back up my trailer without fail the truck will start rattling and act like the engine is going to jump out of the hood. Turning the truck off and back on instantly fixes the issue but that's a poor excuse for a solution.

I've also began to notice that while in part throttle, mostly in low speeds, I can hear a faint, one second or less, burp from the exhaust as if for a second the fuel and/or ignition forgot what was going on for a moment. This is all while keeping a relatively constant throttle position.

I don't know if these are Gryphon related issues or if this is a ford related issue, but any help would be appreciated.

Thanks!

Michael
