hey guys, i got a 345b that idles down by itself. had this problem last year and found the speed sensor wire was rubbed threw and grounding out. fixed it but in the past month its been doing the same thing. just got hooked up with ET and found an active code when the engine hits 1500 rpm, its a 587-2 code, engine governor position sensor. i can't find anything on SIS and i know this engine doesn't have a governor and theres no governor position sensor on the schematic. anyone else ever come across this code?
