    HI all, new to Jeeps and have a few noob questions if I may.

    I have a 2.4 l kj sport.

    Q1 what is the idle speed for the 4 pot? mine is running at 1024 according to my diagnostics gear.

    Q2 It is showing some codes ,

    P0031
    P0037
    P0135 and
    P1491

    I assume the first 3 relate to the O2 sensors being faulty and I assume the 4th is the cooling fan will not work as the relay has a fault.

    whould this be fair?

    Q3 what is the service intervals for oil, cam belt and such?

    Thanks in advance and stay healthy in these serious times

    Many here may not know much about the 2.4 motor, I should be able to help get U the Factory manual though. What year is your 2.4 Jeep?
