I have a 1999 Yamaha V200TLRX 0X66 that will not stay idling. If I feather the throttle enough I can get it above 2000 rpms and it seems like it runs perfect. Anything below the 2000 rpms it sounds like it is misfiring and cutting out. I have put 3 new Yamaha oem low pressure pumps on the motor, replaced the vst high pressure pump and filters, had old gas removed and new put in just incase, cleaned the o2 sensor and the housing, new spark plugs installed. I have read in some places where the CTS could be tested but I do not even know what the CTS is. Any recommendations are appreciated. Thank you.
