Ford Fiesta ST Air leak issue. p2279 p006a

[stedaley]

Getting OBD issues of P2279 and P006A on my 2014 ST3

Had the car in a garage and they can find the issue.

Changed MAF sensor. Had a smoke test on the Air system / recirc. Recirc rocker cover has been changed to fix the power issue i had as well. (130hp was being produced.)

Any other ideas of what to try before taking it back into someone else?

Regards

Ste
