Those had a lot of problems with vacuum leaks causing surging and stalling. Inspect the PCV hose grommet that plugs into the intake manifold. The oil from the PCV system makes the hose swell up and leak. They also redesigned the front valve cover on those. The oil would get into the intake manifold and swell up the orings and bolt grommets between the upper and lower intake resulting in vacuum leaks that cause what your having. If you do go ahead to replace the o rings, it's best to get the 2 kits that include the valve cover, PCV valve, and intake gaskets. You should also get injector o rings. The lower intake gaskets should be replaced too cause they deteriorate with expansion and contraction of the intake and heads. Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

You may have a bad IAC ( idle air control) but try eliminating any vacuum leaks and cleaning the throttle body first. Remove the intake snorkel, have someone hold the throttle wide open for you and scrub the back side of the throttle plate and surrounding bore with an old tooth brush and some carb cleaner. Be sure to spray some into the small holes next to the throttle plate. That should help stabilize the idle. If it still has a problem, replace the IAC. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.   Automotive Repair     Auto Body Repair and Refinishing     Heating or AC Issues     Electrical and Wiring     Brake Systems     Car Stereo Repair Advice     General Discussions     Car Making Funny Noises     Engine Fault Codes     Engine Troubles     Exhaust Systems     Steering and Suspension     Transmission Troubles     Tricks of the Trade Automotive World     General Discussions     Antique Car Talk     Car Shows and Events     The Bargin Bin     Motor Vehicle Inspection     Car Care Tips     Traffic Tickets     Gasoline, Motor Oils, Concept Cars and Engines     Auto Insurance, Financing, Leases, Warranties Truck Repair     General Discussions     Truck Engine Repair     Truck Suspension Repair Motorcycle Repair     General Discussions     Motorcycle Engine Repair CarJunky     Open Posting     Board FAQ's     New Board Suggestions
