AB FC idle hunting while cold

Hi all,

I recently got a 87 GXL and it seems to have an idling problem. When I start the RX7 and the engine is cold the car will idle hunt between 1000 & 1500 RPM. Once it warms up it will idle around 1500 RPM. The previous owner said that the car was ported (I am not sure of what type of port or how to check) but I still think 1500 RPM is high for a ported car.

Any advice on why the car might be idle hunting would be appreciated!
