950G When running fine into a pile of dirt or gravel but when use hydraulics to pick up the bucket the engine starts to flutter and will possible die. release the raise function the engine recovery respose is slow but it will recover. checked the turbo its fine and the waste gate is fine and works. The question i have is what is causing out engine flutter?

Hi, do you mean an engine misfire condition
the first thing I would do is verify fuel pressure ,if that is ok I would remove the return line check valve and check the screen if still fitted and for contamination in the orfice

One of my first thoughts was a leak on the pressure side of the turbo but then you did mention the waste gate is working so I can only assume you are getting good boost pressure?
