My check engine light just came on. '03 Rubi, 4.0 w/72K. Any likley issues to check first before I have a scan done?
You might have your codes right on your speedo cluster. I think you turn your key to the right to turn on the electrics but not all the way to start. Do that 3 times in quick succession and you will see your code or codes light up on the speedo cluster area.My check engine light just came on. '03 Rubi, 4.0 w/72K.

Last time my TJ had this code I found a very loose line under the hood, drivers side, next to the intake manifold. Re-setting that connection and adding a clamp fixed it for me.Light returned even after new gas cap, any likely suspects I should check for evaporative leak error code? Thanks
Ken,Mouse, did you find by eye or did you need to use smoke machine?
