Hello TJ addicts :)

Just to say that I haven’t been able to identify the issue after many months so I have asked a Jeep specialist to fix.

It was the PCM which was sending bad codes randomnly, and they have ordered a new one from your nice country. With a few delay, it has been delivered and the Jeep is running well again :)

It was hard to determinate the origin of the issue and I want to thank all members who helped me to diagnose. This helped to save a lot of money instead to let the Jeep specialist do it :) (about 100 dollars an hour here).

Thanks!
