This 1-4 Option was as known as Skip Shift and was a pure EPA fuel saving idea. GC

Actually also an emissions item. When we had to do emissions testing in Illinois Marc H discovered that during the 1-2 shift our cars got a HC spike which was enough to fail the car. The 1-4 skip shift solved that problem for some reason. When we used to do testing, on my '93 I would always have to switch back to my stock chip (which enabled the skip shift; as you know the skip shift can be eliminated by a programing change on the chip instead of using a plug).
