My engine will stay reved at a higher idle rpm after I blurp the gas sometimes. (it will also slowly climb in rpm until I kill it).  Throddle isn't stuck, so I'm guessing theres a vacuum leak?  Any body have any insight or experience with this?

It's most definetly your secondary butterfly hanging up. carb cleaner will help, spray it on the shaft

I only say throttle shaft gumming up because I've had the same problem. If it was anything else it would not come off of the high idle.. just warm up the car tap the throttle and the idle will be high when you let the throttle off,then grab the secondary throttle shaft and  turn it closed, it will and the idle will be normal. I found out you have to stay on keeping that shaft clean on a weely basis. hope this helps..
