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

My P2279 P006a turned out to be a fault with the throttle body.

Eventually after trying many things I swapped the throttle body with a spare I had on a wrecker engine.

So air leak (or as perceived by the PCM) was on the intake side.
