random misfire
Recently posted about fire on 2 cylinders only. Replaced pcm and is now running much better- but getting intermitant codes that say"random misfire on cyl's. 2 & 5. Have only driven 20 or so miles and have new plugs. Could this require a certain drive cycle in order to "train" the pcm? or any other suggestions. Have replaced all pertainent sensors.
