  • twin 01 250hp 0x66 low rpm issue

    These motors run great anything over 1100rpm ,the port motor will cough and konk out at idle esp when put in gear. these motors have had filtes ,including the vst filter with in the last few weeks, aswell I have cleaned the 02 sensors, This has helped the starbord motor somewhat, I talked to my local dealer and he said to changed the 02 sensor as it may be bad .Do not mind changing it , but do not like to do swapps. I figured i may be over propperd as iin gear it idles at 500 rpms, running 25's , should have 23"s on it , any help would be apreciated. There was another post on here a 100 or so back , but the gentelman , never said what his fix was

        It is listed as synchronizing throttle valves.
