Hi guys.. Just did the error code test on my vn because the idles are fluctuating really bad and sometimes it revs up then drops too low and stalls... anyway did the test and got code 13 (Oxygen Sensor) and 21 (Throttle Position Sensor (TPS) - Voltage Too High). Im fairly sure how to fix the o2 sensor.. but not too sure about code 21.. how should i go about fixing that?
