Let us know what codes it shows and we’ll try to help.

If you plan on owning a TJ for a while, I’d recommend downloading the FSM’s from this forum and invest in a bi-directional code reader.

Good luck!

Much mahalos @RocknLJ. Just got it read. 0122. Throttle pos sensor. Too cool that TJs can do this. didnt have to replace sensor, just cleaned the plug and reconnected. Engine light gone. Thinking of cleaning the butterfly. Thanks again gents.
