The speedometer goes in and out fluctuating from working to not working and has periods of needle jumping. Sometimes it works, sometimes it doesn't.
So i replaced the speed sensor and now it seems better than before as it works more often than it did but it still fluctuating.
My next step will probably be to replace the entire assembly. Currently the sensor and the part that the 10mm bolts attach to have been replaced.
Other culprits besides the assembly could be the sensor wire or the dash gauges.
Concurently my APexi Vafc is not reading any throttle position reading, could this explain part of the problem?
