i have a 2002 dodge grand caravan sprot flex fuel and it kicked out a p0171 code. it started to run like hell. bogged down and sputtering. if i rev the engine it lets out a cloud of black soot./ not smoke but soot. and there is fuel in it. the soot is wet. i changed the MAP sensor and checked for vacuum leaks. no dice. im wondering what your next stepo would be.
