Idle Problem

[Sleepless]

hey guys

wondering if anyone else has ever had a problem like this. Coming to stops my car either stalls or drops the idle down to about 200rpm. If it doesn't stall it makes a slow climb back to about 900rpm. If the aircon is on coming to a stop the idle drops to 200.. climbs up quickly to about 1000 then drops again to 200 the whole time it's stopped :/

Is this a computer problem?

Idle control valve could be the culprit. Depending on what engine you have, it may be at the end of the top part of the intake manifold - the opposite end to the throttle body.
