I have had the "marbles rattling in a jar" upon heavy acceleration or under load, since my truck was brand new. Dealer said it was normal, tech said his Tundra did the same thing. They recommended octane booster or higher octane gas. Believe it or not after several tanks of mid 89 octane Chevron instead of the 87 Chevron it goes away. Recently my wife used my truck and refilled with 87 Chevron, it rattled away until now after I have run several tanks of 89 thru it again.
