you might want to check for a vacume leak, somtimes you can spray carb cleaner around the intake and vacume lines and listen for a change in ideal, i wouldnt have drilled a hole in the throttle plate you might have added to the problem and might now have to get a tune to compensate for the extra air going into the engine. did the surging hapen after you drilled the throttle body or was it already doing it before you drilled?
With cars being so controlled by electronics, always take the time to try many different things before any physical alterations are done.
Wish I could help you out.
Best of luck!
