Can a Clogged EGR valve cause an engine to stall?
Can a Clogged EGR valve cause an engine to stall?
Stalling Your EGR valve operates using a vacuum that controls airflow between the intake manifold and the EGR valve itself. If the EGR valve becomes clogged, there is the possibility that your car vacuum may become too strong and open the EGR valve completely, causing your engine to stall.
How can I check if my EGR valve is OK?
A quick way to check for this is to apply vacuum to the EGR valve and monitor engine operation. Assuming the EGR valve is ok the engine should begin to stumble and possibly even stall as vacuum is applied to the valve and the pintle opens. Your DPFE voltage should also approach 4.5 volts.
What are the symptoms of a bad EGR tube?
Rattling noises from the engine Another symptom of a bad or failing EGR tube is rattling noises from the engine bay. If the EGR tube breaks or comes loose, it can cause rattling noises as a result of the metal tube vibrating. The noise may be quiet at idle, and become more noticeable when accelerating.
How does the EGR work in a car?
The EGR valve recirculates burned exhaust emissions back into the intake system so the emissions can be re-burned, or “recycled,” out the exhaust. The system operates by the opening and closing of solenoid valves, regulated by a diaphragm.

Can a cracked EGR tube cause a rough idle?
Cracked or broken EGR tubes will create an exhaust leak which can cause a rough idle. The idle may surge or stay higher and lower than normal, and may be especially noticeable after cold starts.
Why does my engine make a popping noise when the EGR is closed?
On rare occasions, a clogged EGR valve cause your engine to make a knocking or popping noise. This can occur when the EGR valve is stuck in the closed position and gases build up in your motor. Engine Light Help: Help With Those Troublesome EGR Valve Codes!
