I have a 98 Xj Classic, 4.0 with 165000 miles on it aw4 trans. My jeep has lost all its ***** and is a dog. My check engine light is on and i have multiple cylinders misfiring. So far I have replaced plugs, wires, cap & rotor, coil pack, the crankshaft postion sensor was replaced over the summer. I am at a loss of what it would take to fix it. Someone told me to try the cam postion sensor and I have also heard that I may have bad injectors. Has anyone had this issue before and What can I do to fix it?
