I just picked up an 85 with an erratic idle issue. It pretty much always idled at a little under 1k (which is to high to begin with). Then every once in a while it would jump up close to 2k for between 10 - 40 seconds and there never seemed to be any rime or reason why it went up or down.
So I played with the chock one day, and got it idling at a perfect 800 in neutral and about 650 in gear and it doesn't jump up anymore either. Now according to what I seen and read, the wire to the choke should be down towards the motor, but mines more on the right side towards the front of the car. So it's about a 1/4 turn off from what everyone says it should be, but if it runs better this way, I say their wrong, not me.
But we'll see what happens in the winter, when the choke is actually needed.
