My 16V 4AG has a high idle

[Zero Method]

Well, The engine idles at 1500rpm it starts at about 1200 and go up when it warms up, I turned the throttle position all the way down. 1500 is as low as it goes I checked club4ag and some one had a similar problem but he had aftermarket camshafts are mine are stock. Could anything else be the culprit? or was someone messing with my cams while I was away? Any info would be great, Thanks in advance.:bigthumbu

vac leak maybe. i got alot of vac ports blocked off and when one plug pops off it idles super high.
