Just been out in it after cleaning the idle valve. It now over revs for a few seconds at about 1500rpm then drops down gradually but ticks over like it's surging slightly. Help please!

Hi Guys, I hope some of you can pin point a problem I'm having with my 1997 2.3 Galaxy manual. About 3 months ago it started trying to stall when driven from cold after a minute or so. Only did it once then car would run fine and no problems when engine was warm. Went out in it this morning and same thing happened but continued even when warm. The engine tries to stall but picks up most of the time. Occasionally it does stall. Very annoying!!! I have taken the air flow connector wires off and the engine doesn't try to stall when revved and left to settle again. Attach connector back on and it nearly stalls. Is the air flow meter at fault or could it be a fuel problem? Any help would be very much appreciated!
