The PCV system is designed to prevent blow-by gas from escaping to the atmosphere by drawing it directly into the intake manifold. The PCV valve contains a spring-loaded plunger which is lifted in proportion to intake manifold vacuum. Under high vacuum, blow-by is returned directly to the manifold through the breather chamber and PCV valve with fresh air. When intake manifold vacuum decreases (wide open throttle) and vacuum in the air cleaner increases, the PCV valve closes and the blow-by is returned through the cylinder head cover breather hose and into the air cleaner. The PCV valve also acts as a check valve when the engine backfires to prevent crankcase explosion. Fig. 1: PCV system components-1984-87 1.5L engines Fig. 2: PCV system components-1988-91 1.6L engines Fig. 3: PCV system components-1992-95 engines Fig. 4: PCV system components-1984-87 carbureted engines SERVICE Positive Crankcase Ventilation (PCV) Valve For PCV valve removal, refer to Routine Maintenance of this information. 1. Locate the PCV valve. With the engine running at idle, use pliers to pinch the PCV hose between the valve and the intake manifold. It should be possible to hear the spring loaded valve click shut. 2. If no click is heard, remove the valve from the engine but leave it connected to the intake manifold. A hissing sound should be heard and vacuum should be felt at the valve inlet. 3. If no vacuum is felt, remove the valve from the intake manifold hose. The engine should stall or almost stall. This will indicate a stuck valve or clogged hose. Check the breather hose for clogging or leaks and replace any defective parts. Exhaust Gas Recirculation (EGR) System FUEL INJECTED ENGINES General Information See Figure 3 The Exhaust Gas Recirculation (EGR) system is used to control emissions measured at the tailpipe. Components included are the EGR valve and controls. The EGR system uses a poppet type valve to regulate the amount of exhaust gas flowing into the intake manifold. The flow path is cast into the cylinder head and does not use any external tubing. A control solenoid valve regulates the amount of vacuum to the EGR valve. A Constant Volume Control (CVC) valve provides a constant amount of vacuum to the control solenoid valve over a wide range of engine vacuum. When servicing or repairing any part of the emissions system, it is absolutely essential to check for any obvious mechanical faults or failures. Remember, a trouble code only indicates which sensor or circuit is affected by the problem. Simple mechanical faults such as a vacuum leak or poor electrical connection can cause a fault code. The EGR valve is not simply open or closed but is modulated by controlling the amount of engine vacuum to the valve diaphragm, up to a maximum of 8 in. Hg of vacuum. The EGR valve has a sensor in the top of the valve that reports valve lift to the ECU (same as ECM, 1992-95). The ECU modulates the position of the control solenoid valve to control the EGR valve lift according to an internal program. Upstream of the control solenoid valve, the CVC provides a constant supply of vacuum so EGR control is precise under all manifold vacuum conditions

Figure 1 – Fittings and Vacuum Port Locations INSTALLATION PROCEDURE BEFORE REMOVING OLD CARBURETOR 1. Determine if the distributor vacuum port is timed (no vacuum at idle) or full (vacuum present at idle). With the engine at operating temperature and idling, pull the vacuum advance hose off of the carburetor and “feel”for vacuum by putting your finger on the vacuum port (See Fig. 2) . If your distributor has timed vacuum advance, you will hook the vacuum hose from the distributor to the passenger side vacuum port on the new carburetor. If it has full vacuum advance, it will be hooked up to the driver side port. 2. The stock steel fuel line must be converted to fuel resistant rubber hose. The stock steel line will not connect to the Performer Series Carburetor. Use Edelbrock Universal Fuel Line Kit #8135. This kit contains a filter, neoprene hose, and fittings to adapt to 5/16″or 3/8″stock steel fuel lines (See Fig. 3) . NOTE: After cutting the steel line, remove sharp edges and clean out any chips. 3. Always use a new fuel filter. Failure to do so will void your warranty. 4. You must use Edelbrock Adapter #2696 or Adapter & Fuel Line Kit #2697 when installing a Performer Series carburetor on a General Motors Quadrajet or Chrysler Thermoquad intake manifold. #2697 includes adapter #2696 and fuel line kit #8135. Do not use an open adapter! (See Fig. 4) 5. You must use Edelbrock Adapter #2732 when installing a Performer Series carburetor on certain Edelbrock intake manifolds. In those applications, install the adapter as shown (See Fig. 5)

Correction 1. Visually inspect the tires and the wheels. Inspect for evidence of the following conditions and correct as necessary: 2. Set the tire pressure to 30 psi (205 kPa) COLD. Subject: Shake/Vibration in Steering Wheel, Floor, Seat at Highway Speeds on Smooth Roads (Diagnose/Balance Tires/Wheels) Models: 1998-2005 Buick Park Avenue, Park Avenue Ultra 2000-2005 Buick LeSabre 1998-2004 Cadillac Seville (SLS, STS) 2000-2005 Cadillac DeVille (DTS only) 2001-2003 Oldsmobile Aurora 2000-2005 Pontiac Bonneville (17″ Tires only) • Missing balance weights • Bent rim flange • Irregular tire wear • Incomplete bead seating • Tire irregularities • Mud/ice build-up in wheel • Stones in the tire tread © 2009 General Motors Corporation. All rights reserved 3. Road test the vehicle with the Electronic Vibration Analyzer (EVA) essential tool for a sufficient distance on a known, smooth road surface to duplicate the condition. Record the Hertz (Hz) reading as displayed by the EVA onto the tire data worksheet found at the end of this bulletin. This should be done after a tire break-in period of at least 10 miles (16 km) at 45 mph (72 km/h) or greater, in order to eliminate any possible tire flat-spotting. 4. If the road test indicates a shake/vibration still exists, check the imbalance of each tire/wheel assembly on a known, calibrated, off-car dynamic balancer. If any assembly calls for more than ¼ ounce on either rim flange, remove all balance weights and rebalance to as close to zero as possible. Important: Some GM dealers may have a Hunter GSP9700 Road Force Balancer, or a Coats XR1850 Runout Balancer. Either will simplify Step 5 by not requiring dial indicators. If a Hunter GSP9700 machine is available, it may also be used to measure the radial force of the tire/wheel assembly. A guideline here is 18 lbs or less. 5. While on the balancer, measure wheel runout. If radial or lateral runout exceeds .020 in (0.50 mm) for aluminum wheels (.030 in (0.76 mm) for steel wheels), replace the wheel. 6. After confirming wheel balance and wheel runout, if any changes were made, road test the vehicle again. 7. If the smooth road shake/vibration still exists: Important: THE CONTROL ARMS SHOULD ONLY BE INSTALLED ON VEHICLES IF, AFTER THE TIRE AND WHEEL DIAGNOSIS AND REPAIRS HAVE BEEN PERFORMED, THE VIBRATION CONDITION STILL EXISTS. 8. Replace both lower control arms on vehicles built prior to the following VIN breakpoints. On Aurora, Bonneville, DeVille, Park Avenue, Park Avenue Ultra and Seville models, a newly developed hydro-bushing lower control arm with improved damping characteristics has been released. This control arm is not used on the LeSabre. The new lower control arms may provide an incremental improvement to the vehicle ride. Customers who have become “tuned in” to the shake condition may still feel some shake in the vehicle after the new lower control arms are installed. Refer to Lower Control Arm Replacement in SI (refer to the Parts Information table below for SI document ID numbers) . Important: The completed worksheet must be attached to the hard copy of the repair order. • If a Hunter GSP9700 Road Force/Balancing machine is used, record radial force variation (RFV) on the worksheet at the end of this bulletin. If one or more of the tire/wheel assemblies read more than 18 lbs, match mount the tire to the wheel to get below 18 lbs. Readings of 12 lbs or less are preferable for sensitive customers. • If a Coats XR1850 Runout/Balancing Machine is used, record radial runout of the tire/wheel assemblies on the worksheet at the end of this bulletin. If one or more of the tire/wheel assemblies are more than .040, match mount the tire to the wheel to get below .040. Readings of .030 inch or less are preferable for sensitive customers. • If the RFV or runout cannot be reduced to an acceptable level, replace the affected tire(s) under the guidelines of the GM Tire Warranty. • The screened tire program is only available for the General branded tires used on the Buick LeSabre. Complete the tire request form at the end of this bulletin and fax to Continental/General. • Road test the vehicle to ensure the shake/vibration has been eliminated

Carbureted Fuel System GENERAL INFORMATION On these vehicles, the engine management system is considered part of the emission control system. The major components include the carburetor(s), feedback control system, the air injection system, a throttle control system and the EGR system. The system consists of sensors and switches that feed information to the Electronic Control Unit (ECU), which will then operate several solenoid valves to maintain the ideal air/fuel ratio under all conditions. As useful as the tests found in this section are, the first step in repair or service to engine management systems is still to gain as much information as possible about the problem; when and under what conditions it occurs. At highway speed? At idle only? Only under heavy load or hard acceleration? Wet weather? Defining the problem will eliminate many systems from consideration and possibly point to the affected system. Before diving into an extended electrical diagnosis, take the time to review the basics. Check every vacuum line for cracks or leaks. Check every electrical connector for corrosion or loose pins. Quite often, simply unplugging and reconnecting a connector will break up corrosion on the pins and restore the circuit. Watch out for poor grounds, particularly if the car has experienced major bodywork. COMPONENT TESTING Air Injection System The purpose of this system is to supply oxygen to the exhaust stream at a point in the exhaust manifold that is hot enough to burn off some of the hydrocarbon emissions. The main component is an air suction valve. The valve is spring loaded to stay closed, with engine vacuum supplied to a diaphragm that reduces the spring pressure and allows the reeds to open. The ECU regulates the engine vacuum to the diaphragm by operating a solenoid valve. 1. With the engine at normal operating temperature and at idle, remove the air cleaner and listen for a bubbling sound at the air suction port. There should be no sound at idle, meaning the air suction valve is closed. 2. If the noise is heard at the air suction port, disconnect the vacuum hose at the air suction valve and connect a vacuum gauge to the hose. There should be no vacuum. If there is vacuum and the noise stops, the problem is in the control system. If there is no vacuum and the bubbling sound is still there, the air suction valve is defective and must be replaced. 3. To test the valve, draw a vacuum at the air suction valve diaphragm and listen for a bubbling sound at the air suction port. If no sound is heard, the air suction valve or diaphragm is faulty.
