If your Polaris Offroad Vehicle engine runs irregularly, stalls, or misfires, here are a few things you can check: * **Spark Plugs**: Inspect, clean, and/or replace fouled or defective spark plugs. Also, ensure the spark plug gap and heat range are correct by setting the gap to specifications or replacing the plugs. * **Fuel**: Replace the fuel if water is present or if it's the incorrect type. Inspect and replace a kinked or plugged fuel vent line. Inspect and clean or replace a clogged air filter. * **Connections**: Check all ignition connections and tighten any loose ones. * **Battery**: Recharge the battery to 12.8 VDC if the voltage is low.
