Your problem is fuel related. There is too much fuel entering the engine. If your vehicle has a carburetor, check the float level and needle valve for leaks.(also make sure the float actually floats...some develop leaks or foam type sometimes become saturated and sink) If injected, make sure that the throttle position sensor, map sensor and pressure regulator are working correctly and that the temperature sensor is also good.Last, check any vapor recovery system used...they sometimes can fill with fuel and allow raw fuel to re-enter the airstream and richen up the mixture. After finding the problem, replace the spark plugs as likely by now they are fouled.
As there are a number of items to look at, I can't give you an exact "fix" but if the vehicle was here, those aqre the items I'd look at first.
good luck

2.5 4 cyl engine Code P0171....Black Soot in the exahaust and water...Black soot on the plugs. I have replaced the catc and muffler, MAP sensor, coolant temp sensor, coil, plugs, wires, dist cap,cleaned...


Black soot in water? You mean water in the tailpipe or black soot in the coolant in the radiator? Have you tested the manifold air temp sensor and the throttle position sensor? If they were OK, you may just have worn injectors that are allowing a bit too much fuel flow or a bad spray pattern. In the meantime, you could try replacing the plugs with a set that is one heat range hotter. If the plugs become slightly fouled, that can cause a snowball effect which makes the situation worse.
