A P0302 code indicates a misfire in cylinder 2 of your 2002 Ford Focus. To fix this issue, start by checking the spark plug and ignition coil for cylinder 2, as they are common culprits. If those parts are in good condition, inspect the fuel injector for proper operation and ensure there are no vacuum leaks or issues with the engine's compression. If needed, use an OBD-II scanner to clear the code after repairs and see if it reappears.
