Twin 2001 150 HPDI's - Port motor starts to loose RPM's (2000+ drop) when it hits 5000 RPM. Used the YDS software and got the code for injector. Cleared the code, duplicated the problem, and then no more code. I have narrowed it down to an injector because I switched out the VST tanks and have the same prob in the same motor. So I have eliminated a fuel pump prob.

Questions:
How do I tell which injector is giving me the problem?
What are my options? I know that I can send them out (If I can get them all out of the case).

I'm open for suggestions

If one has a problem it would be a good idea to make sure all are cleaned and working properly. It may save the motor
