    Truck wants to load up when you press brake pedal?

    Idles fine in park, nuetral, if you engage ebrake you can put it in gear and it will idle fine, but rpms drops hard and barely wants to run if your in gear on brake???

    Needs a good bit of running airflow to get the STITs to 0, so I dont think there would be a vacuum leak or it would be getting idle air from there instead of the throttle body airflow?
