I have twin Nissan 90 TLDI's 2006 and the last trip out the port engine lost power, I Couldn't get over 2000 RPM on its own, together with the other one running I could get it to 4000 RPM. I came in changed the plugs and checked the wires for spark and all seems well, also there are new water separator filters canister style (I replace yearly) also are new fuel lines and bulbs (I replace every 2 years) Oil pump seems to be working fine and there is no sign of water in fuel or built in fuel water separators under the cowl. help is appreciated.
