^ good reply . Sometimes driving for a while , stop starting can reset .
This is from elsewhere on same subject ,
" Disconnecting the battery has caused the engine ECU to loose its learnt values including throttle body idle control calibration, disconnect the battery again, reconnect it and switch on the ignition but do not start, leave the ignition on for at least 5 minutes then start the car this should allow the ECU to relearn the throttle body calibrations, "
