Yeah i have the same thing happening with Idle, the reason it does that when you first start is to heat up the engine.If the engine is too cool on temperature then when you start driving you could damage your turbo. also, you could lower your idle after it heats, it best to keep it at 1500 RPM, if lower then that, you will hear your exhaust making pops. one other thing iv learned with talons, is that the gas pedal doesn't go all the way back up. Put a spring on it to pull it up.
I just bought a used 92 eagle talon and found that all the wires that connects to the vacuum are not connected. there was no manual in the car when i got, and i dnt where all the wires should be...
Yeah, eclipse/talon does have alot of problems with the IAC motor being no good, but by your description, it sound more like a vacuum leak, to trace for a vacuum leak isn't fun, check all your vac hoses for cracks just being so old, anything could happen, make sure your intake manifold is not leaking, that's what happened to mine, or the easiest way is to take the car to a shop that has a "smoke machine"
what it does is put smoke into you intake manifold, where ever there is a leak, the smoke will finds it way out, make it alot easy to find vac leaks

This may be an emmissions reduction situation. It may be that the high idle is needed to have the correct air fuel mix, still keep running, and meet regulations. How high does it idle and for how long? And, this is just when you start it, correct?
