could be the injector. If not, tight valve clearances would cause a misfire condition. has any work been done on the engine recently?

Thank you , No I just change the spark plugs and cables after getting the code and the blinking check engine light and also try with a brand new coil pack . after that repair still missfiring after the engine rich the normal temperature. it doesn't misfire cold! and next day didn't misfire in all. so, intermittently but never when is cold. (?) Right now is working ok so I'm still scratching my head but driving it.
