Workshop findings:

 DTC P050A00 (Cold Start Idle Air Control System Performance).
 DTC P050700 (Idle speed too high).
Technical Background
On some of the vehicles, it is possible that the throttle body is unable to lower the engine idle during catalyst
warm-up. This is caused by incorrect basic settings for the throttle body stored in the engine control module, not
due to a component defect.
