the unit won't shift the idle? I always assumed that disconnecting the battery...adjusting idle...then reconnecting the battery...then the idle would adjust. Is this an incorrect procedure....just curious. I assumed it was this way as it used to be this way on many other vehicles I've worked on before. Always disconnected the battery and the ECU usually will reset itself as long as it was a self-learning ability. Anyways...let me know. BTW- Is what procedure is in the tech manual?
