Correct definition - p201c- self adaptation rich at part load
This code is for a air leak really so smoke it if you can.
Its compensating for an air leak somewhere?
There are also several service campaigns for that car.
The latest one deals with OIL thru-out the engine wiring harness. I would look closely at that possibility.
Especially at the cam adjusters. Cam phasing could cause and air/fuel fault.
