Hello. Just purchased a 2001 Cherokee with a 4.5" lift and 33's for my daughter. I'm a car guy and also have a 99 Durango with a 5.9 that I rebuilt last year. I've got a lot of questions as I know nothing about Jeeps and 4.0 engines. Gotta get the check engine light gone and emission tested in the next two weeks to get registered. I need a lot of guidance as I overpayed for it and don't have much money to just throw parts at it.
