[QUOTE="Liv4Spd, post: 9316873, member: 10289"] That sounds a lot like detonation, which often can be tied to a fuel systems or tuning issues. Though, if that were the case, those sounds would be coming from your engine bay rather than your pump. The pump could be going bad and is just not able to keep up with load under throttle. I'd start doing some exploring (check your plugs, and see if they're indicating lean/rich or maybe see if you can borrow a scanner and see if it's throwing any codes.) I'm by no means a mechanic, and there's a lot of other minds on this board that can add more specific information than I. But the more you can find out and share with the board, the easier it'll be for the folks on here to help diagnose. [/QUOTE]
