2009 Cobalt SS

My car keeps going into engine reduce mode, service traction control, and service ESC. It won't boost, rpms go up and down and at one point engine started shaking at Idle. If I turn the car off and then on again It starts driving normal again for a few miles.
I am throwing a P0221 and P2176 code.

anybody ever have the same problems and what you do to fix it?

 

Check your throttle body.

 

^ I was thinking I might need a new one. Do you know exactly what to look for on my throttle bodu?

 

I have a few good LNF throttle bodies

 

^ just sent you a PM.

 

The only thing you can check is the plug. They are sealed.
