VerifiedHi my name is ***** ***** I may be able to help you out. Yes it definitely sounds like dirty fuel filters to me. When a fuel filter plugs, the engine will run well with no load or low load but begin to struggle as the load increases, as the filter gets dirtier the engine will begin to have trouble even reaching no load high idle, I hope this helps, please let me know if you need anything else. Thanks, ***** *****
