Having problems with your 1998 Jeep Cherokee ?
My jeep smokes badly. Black smoke in 2nd and 3rd gear...Why?
If its not an oil issue its will be a over fuel issue. Your running rich. It could be a bad fuel pump or pressure regulator. It could be a bad 02 sensor. It could be a altitude sensor like the MAP sensor Get it fixed because right now your toasting the catalytic converter and will set a code for a bad cat when it deteriorates enough
