Sounds like there's something wrong with both your trucks. There is suposed to be a high "cold idle" so the 87 isn't working quite right. And the 2k cold idle in the 89 sounds a little high. The brakes do trigger an idle up function (as they are vacuum assisted), how long is the delay from dropping to jumping of the idle?
