09 cobalt p0223 problem on 2009 Chevrolet Cobalt
double ck wiring. do you have throttle response?
Make sure the electrical connector is seated in the throttle correctly. Reset the DTC and do a throttle re-learn.
WHY did you clean the T-Body? What type of cleaner did you use, carb. cleaner? No code before?
