EGR valve

Welcome to 2CarPros.

A few things can cause this problem. If you provide the trouble code you got, I may be able to help you pinpoint the cause easier.

As far as the issue, it could be a vacuum leak to the EGR solenoid, a faulty EGR valve, Carbon Buildup in either the EGR or Intake or restriction in the EGR Tube or other component.

Here are the directions for EGR replacement and the pictures correlate with them. I'm adding this to help locate the part and so you can remove it for inspection.

PROCEDURES
REMOVAL
If the EGR system operates incorrectly, replace the entire EGR valve and transducer together. The EGR valve and electrical transducer are calibrated together.
1. Remove the air cleaner lid, disconnect the inlet air temperature sensor and makeup air hose.
2. Remove the negative battery cable.

EGR Tube At Intake Manifold

3. Loosen the bolts at the intake manifold
4. Remove EGR tube bolts at EGR Valve.

6. Disconnect the vacuum supply hose to EGR transducer solenoid.

7. Unlock the connector then disconnect the electrical connector from solenoid.
8. Remove the 2 bolt at EGR valve to cylinder head. Remove EGR valve and transducer.
9. Clean gasket surfaces. Discard old gaskets. If necessary, clean EGR passages.

INSTALLATION
If the EGR system operates incorrectly, replace the entire EGR valve and transducer together. The EGR valve and electrical transducer are calibrated together.
1. Connect vacuum supply tube to solenoid.
2. Attach electrical connector to solenoid.
3. Install EGR transducer into the bracket and snap closed.
4. Loosely install EGR valve with new gaskets.
5. Finger tighten EGR tube fasteners.
6. Tighten EGR valve mounting screws to 22 N.M (195 in. Lbs.) Torque.
7. Tighten EGR tube fasteners to 11 N.M (97 in. Lbs.) Torque.

NOTE: Make sure that the hoses are routed away from the hot EGR tube and Valve and clipped.

8. Install the negative battery cable.
9. Install the air cleaner lid, connect the inlet air temperature sensor and makeup air hose.

Welcome back:

Before you replace the EGR, confirm there are no vacuum leaks to it as well as check the electrical connection to it for corrosion or damage to the wiring. If everything looks good, remove the EGR valve and inspect it to see if there is anything causing it to stick open. Carbon or even wear can cause it to stick. Also, make sure where it mounts to the engine, it is clean and no carbon build up.

Let me know what you find or if you need help.
