Hi, I have a 2005 Volvo Penta GXI-E. My motor recently started popping on acceleration. about 3000 rpms it pops or misfires, and I lose speed. After about a half an hour the popping stops and the boat runs perfect for the rest of the day. I had the injectors cleaned, fuel rail cleaned. Changed the fuel pump, pressure regulator, ECT, MAP, IAC, Rotor and cap, and coil, anti-syphon valve. I don't know what else to do. I can't travel as fast as everyone I'm with until the popping stops. Any ideas? This has me confused as to why the boat runs fine after the popping stops.
