Agreed. It's emissions baggage. (The Decel Valve is located on the right side of the engine, near the middle intake runner ??).
When I bought my car, the line to the valve was disconnected and plugged. For the sake of curiosity, I re-connected it. All it appeared to do, was to keep the motor from dropping back to idle immediately after letting off the throttle. This, I believe has some esoteric effect on emissions. Car runs fine without it, but I did read somewhere it can cause the car to "pop" on the overrun.
