    Hi

    So I have a 2013 Challenger of hich the engine is running too rich, to the point where the engine stalls when idling.
    On a cold start the vehicle starts no problem and runs and idles a bit too rich but it manages just fine. After about a minute it starts to stall at idle.

    I have checked all sensors (MAP, IAT, coolant sensor, O2 sensors). I also changed the injectors, checked fuel pressure (stable at 4bar).

    Everything seems to be just right however it’s just running too rich.

    Anyone can help me on this one?
    Thanks!

    Brand: Dodge
    Model: CHALLENGER
    Year: 2013
    Engine: 5.7l hemi

    Hey victorduchateau,

    let’s start with the basics – do you have any error codes?

    Also, assuming you have a scan tool – could you check the fuel trims?
