No miss fires can come from lean mixture, vacuum leaks, plugs/coils among a few.

Thats why I need the code to give you a direction.

1345 and 1347 are missfire codes with cat overheating and possible failure.

1620 is not listed

171,174 are lean codes

313 is a missfire in the first 1000 rpm and that is a coil.

300 is a random missfire

you did the plugs but there is a lot more.

Compression test, vacuum leaks, clogged injectors, coils, mass air flow are among some of the possible issues
