Default Got diagnostic codes P1129 and P1127, whats the damage?

The title explains it, my MIL was on and its idleing plus/minus a couple hundred off and the car went to restricted mode and only will boost 5psi, however, sometimes after im driving it a little while it will boost back to 15.....any idea what this means?

Nope. Search and find out what those codes pertain to and then we can chime in with some help.

Yeah man, its your mass airflow sensor, you can pick one up at a parts store and it takes 2 minutes to clip it in. Dont go to a garage, they tried charging me 350 to do it and i got one for 147$ and snapped it right in.
