Light comes on sometimes. Engine idles rough. Feels like it has a miss in engine sometimes when light is on.

Yep this is common when the engine is misfiring. I would start with a full tune up including ignition coils which go out in these cars. This guide can help

I would service the throttle body as well as part of the tune up. I have included how to do the job on your car in the images below.

recommended spark plugs are typically NGK Iridium IX LTR5IX-11 or Denso Iridium ITV20. These iridium plugs are known for durability, ensure the spark plug gap is set to 0.044 inches (1.1 mm).

Check out the images (below). Please upload pictures or videos in your response of any problems so we can see what to help you with.
