You want that to be 0% at idle

Now on the other hand the PCM will learn the IAC when the correct perameters are met

Well mine is an LN3 but it uses mostly the same parts...
my revving problem turned out to be a malfunctioning TPS, so make absolutely sure that TPS is working, and make sure it is set correctly. Otherwise i would say it is a vacuum leak, but i am sorta partial to the whole TPS thing...
I am not really sure about those engines, but is the TPS the adjustable kind with the cresent shaped holes or the non-adjustable kind? Make sure that the voltage is rising with the movement of the TPS blade, i found out mine was sending a high signal to the computer and the voltage was not rising with the movement of the blade, guess the brushes were bad or SOMETHING....

Once you do that let us know the results...
If its still a problem we'll see what we can come up with...
Also do you have access to the scantool at any time?

This week we should have access to one, but we are planning to get our own scan tool since Oldsman is going to do a pulley drop soon. For now we don't really have one at any time disposal, but we will soon.

Also, about that whole boiling thing, mine does that too...but i would not know about sensors as LEs don't have crap to tell you anything....just might be as simple as a bad coolant sensor.
