Question about 1996 Jeep Grand Cherokee
4.0 liter 179,000 has new plugs,wires,map sensor, 2 new oxegen sensors. i cleaned thotle body. runs great around town. long runs it gets a code po171 lean cond. some black smoke from exhaust. shakes at idle. when cooled runs grat again and after i clear the code po171. can one of the bosch parts be bad, what else can it be motor is otherwise strong.
Could have a bad map sensor. The Map sensor is located on the throttle body. I have seen countless Jepp that start blowing black smoke when they go bad. That would be a good starting place.
