Hello, I have the exact same problem. The forklift starts to run well until it exceeds half of the accelerator pedal. That's when it starts to lose power but the engine accelerates well. I have changed the potenciometer, engine rpm sensor and it remains the same. I've found that translational solenoids lower the voltage when you do that. It does so both ways. It has changed all the filters and hydraulic oil. It does not fail on the console. If the belt is incorrectly synchronized, how does the LHC module detect it?
