Probably an undetected vacuum leak or sticky AIC valve.
Clean the AIC valve w/ carb cleaner, and clean the throttle plate and throat too. Make sure the nipples to which hoses connect on the throttle body are secure and don't leak.
Check the turbo bypass valve by sucking on the vacuum line leading to it. It should hold vacuum (make sure the hose is actually connected).
Check the charcoal cannister. The valve that lets fuel vapors in may be defective. If it's vacuum actuated, gently blow on the vacuum line leading to it. It should hold pressure/vacuum. The Bentley manual has more info on this component.
Check for cracks/leaks in the plumbing from AMM to throttle body.
