    I need help figuring out why my jeep won't start. It's a 2001 Jx 106,xxx miles
    I have replace the coil pack spark plugs with platinum plugs. Crank sensor. I have pressure to my fuel rail. I also clean my idle air controller.
    It stalled out a few times. Then I tried to get home on the highway. Drove fine most of the highway. Rpms jumped around a couple times. As soon as I got off the highway to lower speed limits I kept stalling. The I was struggling to run smooth. The rpms were jumping up and down a lot and stalling. Help please and thanks. It died on the side of the road before I could make it home. Had to get a tow.

    Did your check engine light come on? Did you over heat?
    I owned an XJ for 14 years. Honestly, it treated me very good. But I do know numerous reasons why your Jeep would act f'ed up. Theres several auto parts retailers that will allow you to use a decoder. That would be my first step. Get the codes. Go from there.

    My check engine light has been on since I bought the car in November. It did not overheat. I did not know that some auto parts stores let you rent their decoders. I will check and see if I can get one. There are three different stores near my house. Thanks for your input.

    I going to guess you have at least one sensor bad. Temp sensor or cam sensor maybe. Get codes read before you replace anything else.
