How to fix irregular engine running, stalling, or misfiring in my Polaris RANGER ETX?
- SScott NguyenAug 4, 2025
To address irregular engine running, stalling, or misfires in your Polaris Utility Vehicle, begin by inspecting, cleaning, and/or replacing the spark plug if it's fouled or defective. Check and tighten any loose ignition connections. Replace the fuel if water is present or if the fuel is incorrect, using the recommended type. Inspect and replace a kinked or plugged fuel tank vent line. Recharge the battery to 12.8 VDC if the voltage is low. Inspect and clean or replace the air filter if it's clogged. Also, ensure the spark plug gap is set to specifications.
