Possible throttle body problems?

Hey everyone. I've recently been having some problems with my 2007 Cobalt SS. It's throwing P0121, P0010, and P0446(which I believe is unrelated).

I removed the throttle body and cleaned it completely but my car is still having problems. When I hit the accelerator my car will chug and not accelerate like it used to, sometimes it feels like the car will stall. Once again its a 2007 Cobalt SS not supercharged or turbo. Is replacing my throttle body the next logical step? Thanks for your time

yeah chances are the internals of the tb are messed up and cleaning it wont fix that. But maybe start with p0010 for the intake solenoid valve ... definitely change that since that can make your car stumble and die out due to having more control over ign timing than exhaust and maybe causing the tb performance issue but if not then yes the tb will require replacement. the 446 code is for the vent valve circuit. as long as the wiring checks out - replace the vent valve
