Durango blowing black smoke out of the exhaust, replaced both o2 sensors no more than two months ago. I am getting the same codes off of the scanner. Neighbor thinks the Cat converter is clogged yet when I gun it exhaust does come out.
An exhaust shop said the converter should be okay, and it could be a fuel injector?? Which route should I take? Should I go after a converter or go with the fuel injector??

Still haven't done anything.. Could the Throttle Posision Sensor have anything to do with this?? This will probably be my next move?? Any help or ideas appreciated!!..
