This is an old thread! Does this code need to be "cleared"? I was getting an O2 sensor code when i got this thing... it was running, just idling, and died. I had planned to rebuild the motor, so I did that, replace spark plugs and O2 sensor (everything was sooty and clogged). Did a bunch of other stuff as well... but just got it all together and still have an error 23. It seems to run fine, no smoke or anything. Have not driven it yet because I am waiting for my son to mount 2 new tires.
Any thoughts would be great...
Oh, I have the service manual and 23 is not a listed error...? Frustrating...
