O2 sensors or ???????
« on: June 16, 2013, 09:40:13 AM »
I have been trying to tune my bike but notice that the rear O2 sensor has a mind of its own.  I replaced the front one which is almost a straight line compared to the rear.  The first purple spikes are when you rev the motor, the remaining spikes are idle. The green line is the rear O2 sensor and during idle it has random spikes. It makes for a rough idle.  The voltages are about a volt and a half different.  Any ideas?
