Okay....you'll need to buy new filters....I don't recall your setup, but mine has a pre-filter and a filter.....both filters are slightly different, so be sure to write down the part number for each. I would recommend getting a second set just to have around. You may have to buy a filter wrench to get the current ones off....sometimes they are difficult to unscrew by hand. Then fill the new filters with diesel and screw each back on. If that doesn't do the trick then a second thing tha comes to mind is I believe our throttles are air activated, and maybe you have an air pressure problem there. Let us know how changing the filters affects performance. Hoping it is just something simple like that. Oh, and when you pull the current filters off check to see if the appear to be clogged.
