Carbon does build up, and a catch of some sort isn't a bad idea.

Generally speaking, EGR is normally run at low to moderate loads, but not at idle or full load. At part throttle, EGR can decrease pumping losses, but it can defeat idle strategies without access to tuning the engine - you'll have to see how it idles. At full load you lose horsepower, which is undesirable for many drivers.

Hot EGR and cold EGR have different benefits and drawbacks.

Is your Jeep's EFI system MAF or MAP based?
