Have a problem with my kobelco SK 60 midi excavator. Under load or heavy acceleration starting at mid range of the rpm band it develops a miss. If i accelerate the throttle very slowly it doesn't miss even in the higher rpm range.If i have it running about mid range and start to work the machine it will also start to miss. This problem developed a few weeks ago . Since then i have done a complete service on the machine including cleaning the screen in the banjo fitting and a new fuel filter . The screen had a lot of crap in it and it was partially clogged . I was hoping that was my problem. The machine has a 4 cyl. Isuzu engine with about 4000 hours on it. I'm thinking it might be a bad injector but would like to hear other thoughts that are out there. Stephen:confused::confused:
