Mysterious Valve Rattle

When Iím cruising at highway speed I hear a faint rattle coming from my engine. It sounds like a gas burner running on cheap gas. Like valve rattle. It stops when I accelerate and decelerate. It happens only at cruising speeds. It's not the AC compressor.

Another problem which is probably related to this. My truck starts great but runs like crap until it's warmed up. I have the latest Stealership flash and it is not throwing any codes.

Anyone have clue? Bad injector(s)? I'm getting real tired of dealing with this truck.
