Default Please help! JB4 - Receiving misfire codes - 06-07-2019, 11:06 AM


I received these fault codes on my JB4. The engine is running really rough along with Drivetrain malfunction displayed on the center console dash screen.

60,000 mile service just completed with all new spark plugs.

Thanks for help!

What fuel and mods do you have?

If you clear the codes it comes back?

Can you post a log for us to evaluate?
