If the level stays consistant you might try drilling a small hole(1/8" or slightly smaller) in the thermostat body to let air out.
Like 64nailhead suggested, get a vacuum gauge on it and record the readings. Disconnect the IAC when its cold just after its started. Note the results. Let it get cool and reconnect. Start it and let it warm up, wait until it starts surging again then disconnect the IAC again and note the results. Be ready to shut it off if it starts to race or stall.
Good idea to check fuel pressure cold and hot as well just to rule it out.
Whats the temp. gauge doing?

Yes my coolant keeps dropping, I can't keep it full. And when I turned off the engine, with the cap off, coolant launched out of the radiator and went everywhere. i haven't checked anything with the electronics/vacuum, (and I'm waiting on a fuel pressure guage) , for surging issues yet. Because I am now staring to over heat from a short ten minute drive to work, it's getting up to the second to the last line I want to guess 240 since the last one is 260 and middle is 210. And i try to top off the radiator but it keeps surging and pushing all the fluid i add out, I've almost went through a jug trying to do this. And I'll check my spark plugs shortly once the headers cool down.
