I have a 154K mile 1988 Cherokee 2-Dr, 4.0L I-6, auto trans, 4WD that my wife bought new. I have kept it mechanically maintained myself, mainly for icy/snowy Oklahoma winter day's commute and as a beater. About a year ago it developed a sudden urge to barely run, belching tremendous amounts of black soot while it does. Enough soot, in fact to completely turn a garage into a contamination zone within a few seconds. In disgust, I parked it. Now, I have decided to try to resurrect it, since winter is coming again. I started it yesterday and it still will make your garage look like a coal mine if it is left to run more than a few seconds. Time doesn't heal ALL wounds, I guess. It seems to me that some enrichening curcuit in the fuel injection logically is at fault, but I don't want to just start replacing parts until I stumble onto the fix. There are no trouble codes displayed. Anyone know of or had this happen to you and have a suggestion for a fix?
