CUSTOMER CONCERN
The engine idles too high after throttle-body cleaning, and DTC P0507 may return intermittently.
CAUSE
The throttle-position learned value was not reset after service, leaving the idle control strategy out of calibration.
CORRECTION
Reset the throttle-position learned value and perform the idle relearn procedure.
