I was receiving codes P0300, P0302, P304, P305.I changed the spark plugs, wires, coils, oil, and oil filter. Car is still missing. Currently, I am only receiving the P305 code. Any suggestions?

Start with a compression test, look for vacuum leaks, test injector and check for wire harness issues as well.
