If the connector is disconnected from the ECM or the battery is disconnected, all adaptation values in the control module 
are erased. DTC memory content will remain intact however. If the engine is started after this, a rough, uneven idle can 
result. In this case, engine must be allowed to run at idle for a few minutes until adaptation procedure has been 
completed.
