running rich, plugs are black and dry.

[chad300zx1990]

i've been searching and checking things all day and cant seem to figure out what my problem is. i just got the car running again yesterday. now its running rich, blowing some black smoke, and fouling spark plugs. when i take the plugs out they are completly black but not wet with gas, they're dry. i've redone and cleaned all my grounds, my mafs seems to be getting to much voltage coming from the signal wire, about 2.3volts. tps checked out fine, as did the o2 sensor. the ecu coolant temp sensor is also getting some weird readings. but the strange thing is that the plugs are getting weak spark and their not gas soaked so its kinda like im not actually running rich as much as im just not getting strong enough spark. running bkr6e copper ngk's.anybody had a problem like this??got any advice or suggestionspeacechad

Try swapping out the MAF with another one. Mine does the same thing and it's cause mine is shot.

replace coolant temp sensor and make sure plugs are gapped properly
