Something to replace this procedure:
Manual process
Disconnect the negative lead from the battery for a minimum of 45 minutes. Some people recommend overnight but that is not really necessary.
Reconnect the battery negative lead
Put key in ignition, turn to MAR and leave for 90 secs
Turn off the ignition, but not remove the key and leave for 90 secs
Start the engine but do not touch the throttle and let the car idle for 15 mins otherwise the car will not rev freely afterwards (as V6 owners know at their peril)
Turn the car off and leave for 10 mins
Start the car and take her for a blast
