FAILURE CAN OCCUR RANDOMLY AND WILL RESULT IN LOSS OF POWER TO THE MOTOR UNDER ACCELERATION. THE PROBLEM AFFECTS THE 2004-2005 MODEL YEARS. SPECIFICALLY THE SECONDARY THROTTLE VALVE ACTUATOR (STVA) <AKA INTAKE VALVES> CAN FAIL AND RESULT IN LOSS OF ENGINE POWER. A FI (FUEL INJECTION) CODE DISPLAYS ON THE DASH. ONCE YOU ACCESS DEALER MODE, THE DISPLAY CODE IS C-28. THIS IS DUE TO FAULTY SOLDER CONNECTIONS WITHIN THE STVA MOTOR. ATTEMPTS TO CONTACT THE MOTOR MANUFACTURER RESULT IN BEING TOLD TO GO BACK TO THE MAKER OF THE MACHINE THE PART WAS FOUND IN. AFFECTED STVA MOTORS FOR THIS YEAR WERE MANUFACTURED FOR ASTROSYN BY A COMPANY CALLED MINEBEA. NOW KNOWN AS EMINEBEA.
