[QUOTE="JamesK, post: 1176786, member: 1858"] Having confirmed that disconnecting the O2 sensor did not fix the idle stalling problem I reconnected it and unplugged the PCIII USB last night. It was late so I couldn't properly rev up the engine but it seems that the bike is idling much better now but seems to still have a bit of an occasional stumble. [B]As far as I know the O2 Sensor has the most impact at low RPMs so I am wondering whether at 208k the O2 Sensor might not be functioning at 100%? Are there any tests that can be run on the O2 Sensor which could confirm proper operation or identify common failures?[/B] Despite the obvious implications of a spend on a new/replacement Power Commander I'm hoping this was my problem (or at least for the most part, the O2 Sensor is still a second suspect), will be able to confirm on a ride this weekend. While searching for used PC units for sale I [URL="https://www.fjrforum.com/forum//index.php/topic/148292-possible-power-commander-iii-problem/?do=findComment&comment=1000296"]came upon this thread by Hornet Pilot where the symptoms sound very similar[/URL], and in that case the culprit was the PCIII.
