97 2.3L Bad idle...
Recently found a ranger in a field, bought it, replaced the head that was cracked and it ran fine for the first 7 months or so. About 3 weeks ago though it started having a gassy odor/burnt water odor when driving. It also started idling crazily at an idle, up then down to a near stall out, if i stomp on the gas though it will go away and idle normal for about two mins then do it again. Once in gear and going it runs fine..... more of a diesel junkie so im stuck on this. Any help would be appreciated.
