What's wrong with my car

Check engine light on.8 codes. 2 are old, which are the knock sensors ( they both have been replaced along with the wiring harness), yet the codes still show. Can smell faint gas fumes starting 2 days ago. Today all of a sudden car started stumbling and 6 more codes . P0441 (code shows twice) P0120, P0300, P0304, P0305.

P0120 is a diagnostic trouble code (DTC) for "TPS "A" Circuit Malfunction". The throttle position sensor circuit has a short or malfunction.

The P0300 series codes indicate both random and cylinder-specific misfires
Faulty spark plugs, faulty plug wires, worn/faulty fuel injectors -to list only a few possibilities.
