Well unfortunately I started the trip yesterday and the starboard engine would not increase above 3000 rpms. Generator started making a clanking noise which was a rocker arm that needed to be secured back down.

I never got out of the Galveston Bay after filling up with fuel. New plug wires and a new IAC Valve but that did not help. I am wondering if (you guessed it) trash from the tanks clogged up a fuel injector or two after filling the tanks.
Engine seems to be fine without a load, fuel pressure straight from the fuel pump is running 40-42 and 32-34 should be sufficient. Remember I replaced the fuel pumps and filters as well as the fuel regulator.

These engines are nothing more than standard Chevy 454 3500 series truck engines I learned yesterday.

We are replacing the distributor this morning with a complete assembly because it was replaced as piece set recently.

If nothing else at least the generator is purring and I didnt get stuck in the ditch. I shall see how today goes.
