Check the oil pressure with a mechanical gauge-if normal replace the oil pressure sending unit-abnormal-could mean engine bearings/oil pump/clogged pick-up screen/sludge etc.

when i flutter the gas it sounds like a bunch of marbles.

Could be the EGR valve not opening and causing the engine to detonate/ping-does it sound like -when you throw in a bunch of marbles in an empty can?

Idle the engine and start removing plug wires one at time the one that lessen the noise is the trouble area
