Thread: 1991 4.0 YJ tune up

  1. #1

    Question 1991 4.0 YJ tune up

    It is time for me to replace the spark plugs and plug wires on my 1991 4.0 YJ. Should I also replace the distributor cap and rotor at the same time? They are not expensive at all.

    Do I need to go as far as replacing the entire distributor? I think the cam sensor lives in it.

    Thanks in advance.

    I would replace the cap and rotor as well.
