    what did the emision tester say that was off ?
  • they did not tell me anything specific yet. i can see why it is not reading it because someone unplugged or cut some wires off so the engine light would not come on. they just wished me good you know anything about it?

    best bet would be to try and get the wires reconected to the obd plug (assume that is where the wires are cut ) gust match color to cut wires and splice them together then you can get a read out of the computer

    dont know if your jeep can read throught the speed o meter or not by turning the key of and on
