  • check engine light

    my 98 4 cyl is giving me a check engine light I dont have any diagnostic equipment whats the best way to figure it out?I was told it could be the ignition pick up or cap but it doesnt make much sense that it went from runnin fine to runnin like crap over night it starts to miss at 2000 rpm and got hard starting

    Not sure if the 98 will do this but in my 05 pickup and 03 minivan if you get in the drivers seat, shut door, insert key in ignition and turn on (dont start) and off 3 times, ending in the on position then the odometer will display any engine codes.

    Again not sure if this works for your application but may be a good way to check

    Get the codes and look them up. This will give you the problems.

      Either try here: http://jeep-forums.4wd.com/showthread.php?t=509
      or take it to Advance Auto and they will read the code for free.

          TJ's do codes to different ways...
          check the thread Buster posted.
          If you're getting no codes then "nothing is wrong" and well... you have a Jeep.

          Try Autozone for a free OBD II read...

          Also, air filter clogged?

              I think every 60k miles is the recommended change-out for the timing chain. If that's stretched then you'll get errors... you also run the risk (if you let it go too long) of the chain breaking... and a little resulting incident with the valves that you can post up carnage pictures of.
