Around 2060 hours on machine. 2018 model. Between 1350-2100 rpm’s the engine will sound like it’s got a hiccup or slight miss about every 2-3 seconds. No symptoms below or above those rpm’s. Fuel filter is full. Starts right up and idles fine. Any suggestions on what to check on or try out?
Please post a Serial Number to help in obtaining accurate information. Is this the same DX203721 that you posted about before.? Have you drained the water separator bowl in the bottom of the fuel filter recently.? Have you checked the inline fuel screen for any signs of blockage.? Do you know how to access Diagnostic Codes in the electronic control system.?
