Maf was cleaned new air filter and all plugs new and new coils on 1,3,5 when the new cats were installed. The codes seem to change on a daily basis?

Maf was just cleaned before the cats got red, last week it was cylinder #1 misfire?

You're really going to need to hook it up to a diagnostic computer so the Fuel Trim and other monitors can be watched while the engine is running. Obviously, guess work hasn't fixed it yet.
