I have a 1997 Challenger that simply won't rev at all. When I open the throttle past half throttle, it will either just bog and stall or stay at the rpm it got to at half throttle. I have pulled the air cleaner assembly and the throttle blades are operating correctly. The choke is not sticking. I have disassembled the rav valves and cleaned them. I have installed new plugs. I am about to install new fuel filters as it does act like it is starving for fuel. It does fire right up and idle well but nothing much else going good here. Can anyone suggest other remedies?!?

Took it into a qualified mechanic and the prognosis was the jetting. I bought the boat off of Ebay from Florida. I am in the Rockies. The boat was running too rich and the exhaust valves were caked with carbon from the condition. New jets and a valve clean along with a good tune and the boat is a rocket.
