Odometer is broken, so keeping track of use in gallons. Ran about 60 through so far. Getting some harder starting, slight miss around 2000rpms, and noticeable loss of power, especially on the low end. Changed the fuel filter with no real improvement. No bubbles when cracking injector lines or fuel filter banjo fittings. Added an inline electric fuel pump, no difference.

Coking up injectors and/or prechambers? I'm busy right now and this a beater so my plan is to run a few gallons of D2 with a strong dose of Stanadyne performance formula for a day and see if that helps things. I'd like to check the injectors and prechambers for carbon build up when I get a chance.
