Why does my Polaris 2005 Predator 50 Offroad Vehicle engine run irregularly, stall, or misfire?
- KKatie RodriguezAug 5, 2025
Irregular engine running, stalling, or misfiring in your Polaris Offroad Vehicle can stem from several causes. It could be due to fouled or defective spark plugs, which should be inspected, cleaned, or replaced. Other potential reasons include loose ignition connections (check and tighten them), water in the fuel (replace the fuel), a kinked or plugged fuel vent line (inspect and replace), or a clogged air filter (inspect, clean, or replace). Low battery voltage (recharge the battery) or incorrect fuel (replace with recommended fuel) could also be the culprit. For worn or defective spark plug wires, electronic throttle control malfunction, or other mechanical failures, consult your Polaris dealer. Also, ensure the spark plug gap is set to specifications.
