My 97 7.3l powerstroke van has started to idle rough but only when warm. At cold start is sounds/feels normal. At any RPM other than idle it also sounds and feels normal. When idling warm it is very rough, periodic vibration that feels like it is stalling. It has not actually stalled, there is no smoke at warm idle. Some smoke at acceleration from idle but none accelerating at higher rpms.
From other posts the cam position sensor might be worth replacing. It also smokes alot on cold start until warmed to normal. More smoke than there used to be on start up before the rough idle. It has 305k on it already so some smoke should be ok. Any ideas?
Thank you
