ok so first and foremost new here and I would like to say hello. This is like my 7th jeep and I love them this is a 97 Cherokee SE 4.0 Auto
now onto the issue. This jeep runs really rough at an idle and exhaust smells like fuel terribly. has a pretty good miss to it. now under throttle this thing makes good power and runs smooth will run down the freeway at 75 like a champ. when I first got the jeep home I had noticed that the throttle body bolts were all loose so I tightened them.
first off I have a cracked factory manifold I am going to replace this with a header (this could be part of the running issue perhaps?)
I have replaced the cap, rotor, plugs (W/Champion), wires due to it having cylinder misfire codes. reset the engine light and withing 2 days it was back on with the same code. Can someone please enlighten me on where i need to start looking next?
sorry for the long winded description any help would be greatly appreciated
