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

The issue could involve replacement of the PCV plate etc.
What has been done so far?
