Another argument against the four barrel. A four barrel carburetor typically has vacuum operated or progressive linkage on the secondary barrels. The EFI systems do not. All four barrels open at once. This can cause the throttle to be very touchy off idle and at low speeds. A little throttle movement lets in a lot of air. Exactly what you don't want in a Jeep. A right-szeed two barrel witll have much better driveability.
