Okay guys. 95 pcm gt40 motor mpi. Boat runs like a top. Idles smooth. When It gets to 2900 Rpms it starts surging and won't get any higher. Back it down and it runs like a top again. I picked up a new fuel filter separator but haven't put it on yet. Anyone have any ideas. I'm also going to change the cap rotor wires and plugs while I'm at it.
