200 HPDI missing at all speeds

Compression good, what are the most common causes for an engine running poorly at all speeds, fuel or ignition?

Either one and more, the fuel injected engines have sensor that can also cause it run bad.

YDS showed everything is normal. Problem turned out to be a clogged VST pump fuel screen. Pita to clean that puppy. Strange that it clogged given the fact that both the Racor and the 2 engine filters have less than 50 hours on them.

The debris that clogs the VST filter(2 micron) is very fine and passes right thru the RACOR(10 micron).

I experienced the same problem and it was likey due to ethanol cleaning the inside of my aluminum tanks.

FWIW, the VST filter is a 200 hour mait. item.

change your plugs. 40 bucks well spent. also yours one of the motors with the oil pump recall?
