NOTE: The system has a learning ability which allows it to make corrections for minor variations in the fuel system to improve driveability. When the battery is disconnected the computer's memory is cleared and the learning process has to begin all over again. A change may be noticed in the driving performance of the vehicle. To reset the vehicles learning ability, make sure the engine is at operating temperature and operate the vehicle at part throttle, moderate acceleration, and idle conditions, until normal performance returns.
