Need to find out where my egr valve is located on my 2003 impala

SOURCE: EGR VALVE

REMOVAL PROCEDURE

1. Turn OFF the ignition.
2. Disconnect the EGR valve electrical connector.
3. Remove the bolt retaining the pipe assembly from the EGR valve and carefully pull the pipe assembly back.
4. Remove the EGR valve retaining bolts.
5. Remove EGR valve assembly.
6. Remove the gasket.

INSTALLATION PROCEDURE

1. Install the EGR valve with a new gasket to the intake manifold. NOTE: Refer to Fastener Notice in Service Precautions.
2. Reinstall the bolts through the EGR valve into the intake manifold. Tighten Tighten the EGR bolts to 30 N.m (22 lb ft).
3. Connect the exhaust pipe assembly to the EGR valve.
4. Reinstall the exhaust pipe bolt. Tighten Tighten the nuts to 30 N.m (22 lb ft).
5. Connect the EGR valve electrical connector

SOURCE: WHERE DO I LOCATE THE EGR VALVE ON MY 2001 CHEVY IMPALA 3.8 V6

The egr valve is located at the end of a hose that plugs into youe valve cover. It is pushed right into a rubber grommet that is located in one of the valve covers. I hope this helps. don.t forget to rate my nswer, thanks

SOURCE: FAILED EGR VALVE

The EGR valve helps your car more efficiently and completely burn fuel by recirculating a portion of your exhaust and running it through the combustion process again. This results in a cooler, more complete burn of the fuel which decreases you car's noxious emissions by prohibiting the formation of some harmful gases.

The EGR valve is vital to your car's emission controls.

When the EGR valve goes bad, it must be replaced - it cannot be repaired.

EGR Valve = Exhaust Gas Recirculation Valve.

The EGR valve controls formation of noxious emissions.

Rough idle and poor acceleration can be caused by a faulty EGR valve.

The EGR valve, or Exhaust Gas Recirculation valve, is a vacuum controlled valve which allows a specific amount of your exhaust back into the intake manifold. This exhaust mixes with the intake air and actually cools the combustion process. Cooler is always better inside your engine. The exhaust your EGR valve recirculates also prevents the formation of Nitrogen related gases. These are referred to as NOX emissions, and are a common cause for failing emissions testing. Unfortunately, your EGR valve can get stuck, causing NOX gases to build up. You'll know if your EGR valve is stuck or malfunctioning because your car will experience symptoms like rough idle and bucking on accelertaion.

The only short term problem is a decrease in gas mileage - but it should really be replaced before sensors become sooted or your cat. convertor gets overworked prematurely.
