My Cherokee has 130k miles on it and was running fine until yesterday. I have had other problems over the past few months, so it has had the several new parts installed. (CPS, plugs, wires, cap, rotor, coil, fuel pump, complete exhaust, 02 sensor) All these parts were installed several months ago and it has been running fine. Now it will start up and idle just fine, but it will not let me accelerate at all. Any attempt to push in the throttle causes the engine to start to run rough and act like it is trying to backfire. The tailpipe starts spewing out black smoke, too. It just will not go over 1000 rpm's. Any ideas on where to start?
