Remove the air filter off the inner backing plate and you will see a hole in the lower right hand side of the backing plate, inside that hole is the screw to adjust the hot idle, they usually lose about 100 to 200 when putting the air filter back on so be ready for that. Make sure the stepper motor is releasing the cold idle before heading towards the hot idle screw, the ETS controls the stepper motor and someone might of tried adjusting the cold idle with the ETS messed up.
