I would start with a tune up, new spark plugs and wires, also service the throttle bore and IAC. I have also seen the coil pack go bad, but I would start with the plugs and wires. This guide can help walk you through the service with instructions in the images below for your car:

and

Spark Plug .................... AC Type 41-940

Check out the images (below). Please let us know what happens.
