This forum has very little traffic. You will have more responses if you post your questions and concerns on rx7club.com or rotarycarclub.com. I do not have a 3rd gen. but a surging idle is most likely the tps sensor.
To address the question about carbon build up: Any car that has been sitting for 3 years needs the fuel system addressed (Gas Tank boiled and sealed, fuel filter change, and possibly even the injectors serviced) before starting it.

When the A/C is on, what RPMs is it idling at?

I'm figuring when the a/c comes on, its not really idling since the a/c puts a load on the engine. Just as if you were to hit the gas lightly and hold it at a certain rpm. Let me know if it makes sense, I'm terrible at explaining things.

lol, you are not the first that has been the problem. The 2nd gen's won't start and act like they are flooded or out of gas. <~ ask me how I know..... lol
