Hey guys I have read countless threads on the first code but I believe I am having a deeper issue here. I have a 2009 cobalt ss turbo with injen charge pipes, k&n intake and gms1. last night cruise control was set to 60mph in 5th gear. out of no where the car starts to like chug and sputter almost if the RPMS were to low and CEL popped on. so i dropped it down to fourth gear then went back to accelrate to 60mph.. well it started doing the same thing and wouldnt let me over 45mph... no boost, and engine was shaking terribly.. and the CEL start flashing at me. I read codes this morning and those were the only 2 to pop up..

All help is appreciated!

 

The MAF sensor might be bad. Both codes point to that. You can buy some MAF cleaner and try to clean it. Its possible you got oil on it if you over oiled your air filter at one point.

 

Probably a boost look. Check your intake and all charge pipes. Did you hit something or large bump?
