get some carb cleaner(spray can). run the engine and spray shots of it around areas that you think have a leak. you will notice a difference in rpm while spraying carb clean when you find the leak

did you check the timing. I retarded mine(just until i'm done with smog) and it came back down to about ~650, but i still have the throttle stick problem that you have. By the way, what color is you car. we basically have the same car and it's interesting how they are having the same problem at the same time.

They sell a vacume guage at about any parts store, is cheap too. thats best accurate way to check. Needle bounces, you have issues. Needle steady, it is fine.
