I checked the speed sensor and I get continuity the specified 4 times per revolution but in between I get approx 6 ohms of resistence. Should it read open or infinity. If I leave the speedometer cable disconnected the engine runs fine. Lots of power and no missing but the warning buzzer sounds almost costantly unless I lower my speed to just above idle. If I connect the speedometer cable back up then I get the intermittant buzzer and engine sputters at various speeds. Any thoughts or suggestions?
