Hello,
I have twin 200hp HPDI's and I am usually VERY happy with them. This weekend I took a trip about 80 miles away and back, totalling about 180 miles roundtrip. So long as I kept the RPM's under 4500 I had no problems. When I went to full throttle, I am only getting about 5000 RPM on the port engine, and with the decreased power on the port engine I could only get about 5300 RPM's on the starboard, while usually the 2 engines will top out at 5700 RPM when they are running right. Beside having a top end issue, a couple times the port engine would intemittnely droped in power. It was like it went into safe mode, dropped the RPM's and then went out. I had no warning lights / sounds nor the check engine light, no warning ever. I also have a VERY ROUGH idle on the port engine.
Since I had to make the trip back 60 miles I kept the RPM's to about 4000 / 4500 without any problems at all.
Before the 200 mile trip I cleaned the inline fuel filter / water seperator, the engine fuel / water seperator, and drained the vapor seperator in the engine. I have also run about 250 gallons of fuel with a fuel injector cleaner hoping it might help.
What can it be?
Thanks! Looking forward to hearing your thoughts.
