Vacuum leak. Check the large duct from the AFS to the throttle body. The bosses for the large vacuum tubing crack at the base.
Also could be a vacuum leak in the brake booster diaphram. Or some of the large vacuum hose connections are cracked. Check at the idle control valve and the engine crank case scavenger vavle. Check all of them!
