Thanks for the replies.

Update... I did some searching and found out how to adjust the fast idle thermo valve, so i did just that... took it off, screwed the plunger all the way in, put it back on the car, and fired her up.... but still surging like before. So i did the following things:

1) bled the air out of the coolant

2) adjusted the FITV

3) checked for vaccuum leaks using unlit propane torch.. found no leaks

4) checked TPS as mentioned above... TPS is good- .488V at fully closed throttle, then 4.3 or so at full open blade

5) made sure all the bolts were tightened for the TB, IACV, and FITV, and the intake to the engine itself

5) i had the inlet tube off the whole time... i did some testing with the two ports on the side of the TB... when the car is warm, it is still surging. but when i put my finger on the upper port (the one for the IACV) the surging goes away. I took the IACV off and put 12V accross the terminals, and it clicks just like its supposed to... I then unplugged the connector to the IACV, and it reads 12V to ground.

When the car is warm, is the IACV supposed to still be sucking air into the intake?

So correct me if I'm wrong, it seems like something is activating the IACV when its not supposed to (i checked voltage to the connector and its reading 12V when its surging) and its making my idle bounce up and down by giving the engine too much air????

So what controls the voltage to the IACV? Is it a sensor or something? Can the IACV be bypassed, and what are the effects of doing so?

And also the surging only happens with the car in Park or Neutral!!!

Please help, i'm at my wits end, i'm thinking of driving it into a river, or just bringing it to the dealer!!!!
