After running WVO (2 tank mercedessource system) for 15,000 miles, i decided to pull out my injectors (monarch nozzles) clean them and bench test them. They all pop between 1850-1950 psi. I also, changed the copper washers and o rings on my injection pump and reemed/replaced glow plugs and glow plug relay.
after putting everything back, purging the air and assuring that there are no leaks, i have very little power under 2500 rpms. The engine also vibrates more than normal in park/idling until i rev it up to about 1700 rpms. It is not smoking much at all. I just cleaned/replaced all filters. WHAT HAPPENED?
Thanks.
