    Hi to all,

    I have a ‘09 Grand Cherokee 3.7L, it idles rough and stalls.
    I connected the handheld scanner and it says 0 DTC but it is flashing CAT, EVAP, O2S, HTR, and EGR,

    Can anyone help me?

    Check your spark plugs and coils. Ensure that there is a spark from your coils and Ensure that your plugs are not damaged, has excessive soot build up, wet. If so, replace them!
