And now I also notice it sounds like theres a knock in the engine while idling. And the rattling seems to come in the first little bit I press the accelerator at idle and then it goes away.
Oh Jeez dude, I didn't want to bum you out but that's what I meant when I said this:
There are other - more serious - reasons that will cause an engine make the sounds you describe, but eliminate the simple stuff first.
What is your oil pressure at idle?
Does the sound get worse when the oil is warm?
Get under the truck while it's idling and making the noise - and check the area around the flywheel.
While idling, pull the plug wires one by one and noted whether removing a particular wire causes the noise to stop.
