hydraulic problem hi ranger linesman 2

[bamf1luke]

Hello,
I'm having an issue with my hydraulics on my hi ranger. the hydro pressure cylces up an down constantly which cause the engine to change rpms. It seem like the unloader valve may be worn out. I know the reason of the rpm change is because the pressure rises and moves the throttle clylinder(moving the throttle linkage). It acts like the pump is switching on and off(i know this isnt possible). The acummulator is charge correctly, pump will build good pressure, full on oil, not a filter or strainer problem.
Is anyone familiar with a linesman 2, or a hydraulic problem like this? Any help will be appreciated! thanks
