Hopefully someone will recognize these symptoms, and be able to help me out.Recently the 4.0 liter started idleing rough, and the smell is real bad almost like carbuerator cleaner. the tailpipe is now black and never was before. Seems like it's running super rich. Plugs, wires, cap, rotor all changes about 200 miles ago it ran a little better. Today on came the engine light so I'm suspecting a sensor. Does anyone recognize these symtoms. Won't be able to get the engine light checked for a few days. Thanks guys.

 

It could be a number of things man.

Wait till you can read the CEL and go from there.
