Accepted Answer

22450 means fuel air mixture too lean, oxygen sensor unable to act and 22451 means fuel mixture too lean when idling. I would start by replacing the oxygen sensor and if problem still exists do a fuel pressure test. Fuel pressure should be 42 psi if low replace the filter which is part of the fuel pump assmebly. Another thing you can do is check for vacuum leaks, intake gasket leaks, turbo piping leaks, and throttle body leaks. Let me know if you have questions, thanks.
