    I been having the same trouble with the same machine . The mechanic told me that oil was getting into the airbox and contaminating the oxygen sensors . I believe they had a recall on the oiltank they had a default in the tank . The dealer was speaking to polaris and they agreed to replace the tank and pay the labor for free as it was a problem from the start . You may also need to check the impellor housing as that is known to swell out and slows the inpellor down . This causes the machine to limit the rpm so it does not burn out your engine . Also you may need to check your compression .
