1993 Pontiac Sunbird 4 cyl Front Wheel Drive 183, 00 miles

When I first start my car, it will " rough" idle for a minute or two, and then I can " hear it smooth out".
My brother says that the " choke is doing its job".

What things do you think might be causiing the problem?

Choke? Is it electronic fuel injected? If so there is no choke. Only carbed engines.

I woudl suspect a faulty IAC module for the rough idling first off.

Maybe even a vaccum leak will cause this or dirty throttle body.
