Hello
I'm in need of expert advise
xb9sx 2005
started to misfire, did a tps reset, and now she cant hold idle revs on its one, flames from the inlet and cots out
already seen plugs(replace them), wires, going for a new O2 sensor tomorrow, but I've read that the temp sensor can have an effect on the fuel timing thing, and the injectors can be dirty
what do you think? she's been running good for 6 years now
thanks

Suspect bad TPS reset.

Idle screw backed all the way off, throttle snapped fully closed, perform TPS reset (reflash ECM with TPS voltage), then set to approximate idle, start bike, adjust idle.

Check TPS output voltage to ensure it is in required range.

Select user account control from the control panel. When it comes up there should be an option to turn user account control off.

I have no issues with UAC on if I rightclick the ECMspy icon and pick "Run as Administrator".

My advice, go for the unexpected, it's always what I'm not expecting that is wrong
