First of all, I would remove all the spark plugs. Make sure the hole is clear if Gas, Oil, Water...

Chek the distributor cap, roter, wire afterward. If you have not changed it in last 2 years, replace with new. The are not too expensive.

Then clean out throttle body if you have not cleaned in last 3 years.
Check all intake air hoses, replace the ones cracked or leaking air.

Your car idle is controlled by Bosch Idel Control valve, you can take it out and clean it as well.
