Rolling idle
My 1991, 21K mile has a rough idle, it sort of has a rolling action. I have changed plugs, air and gas filters, pcv, dist. Cap, rotor, wires, and have used Techron. As I have made each change, I saw no improvement. It starts and runs fine otherwise, no hesitation, and great pick up. While idling, I may give it a little gas to keep it from stalling; once in a while this will cause a stall, and then be hard to start. I believe this is the result of me flooding engine.

In front of your TB, there's a little hole in the middle on the bottom. VERY easy to get too.
With car running, spray some carb cleaner in the little hole, rev engine, repeat 4-5 times.
Your engine will bog down while doing this, no problem
You're cleaning your IAC.
If this impproves your idle, replace your IAC, or keep it clean.
Hope this helps, did for me.
