Don't use WD-40. It causes rubber to swell.
Use carb cleaner or throttle body cleaner on the valve while the car is
running. You want the solvent sucked out as quickly as possible so it
doesn't damage the valve or deposit soot farther down into it.
Also check: thermostat, EGR valve, and PCV valve

I'd check your Fast Idle valve.

Just Wed. of this week, my favorite import car mechanic "cleaned the PCV
valve and adjusted the idling" on my '89 Civic that had the exact same type
of problem. The vehicle now idles perfectly normal. He also mentioned the
following other things that can lead to this type of problem:
-Faulty fast idle valve
-Bad distributor that "can throw the timing off"
-Faulty IAC valve
-Faulty PCV valve
-Improper idle adjustment
