Idle problem; bounce from 1500 to 2100, and back again. (resolved), Click this thread if you want to see some shear stupidity on my part.. Options

This car just seriously hates me. My idle bounces from about 1500 RPM's to 2100 RPM's and then back again, over again, pretty rapidly. Also, there is a LOUD sucking sound from the intake manifold, and if you plug up the IAC hole, the sucking sound goes away and it calms down a bit. This car can be in gear, and actually just pull itself without me giving it gas, and i can shift all the way to forth without giving it gas.

Also Im almost positive there should be a gasket between the throttle body and intake manifold. I hear you on the whole spraying flammable things into a running engine..... ive done it too, but aside from hearing it, checking them all individually, or running a smoke test, thats one of the easier ways to do it. You can also take needle nose pliers and pinch hoses until you hear a difference.

Metal gasket last time I did mine.
