hello. i have a problem with my motor misfiring when i shift and when i cruise in 5th. hopefully someone can help. my car runs fine when its cold, but after awhile. it bogs and stutters pretty bad when shifting and cruising. specially underload or uphill. it started happening when my plugs went bad, i think. so i replaced them with new ngk iridiums. it runs better, but it jerks most of the time now. i do not know what to do. lol. hope someone can help. thank you
