EGR valves are usually activated by a vacuum line from a thermal sensor. It could be leaks in the vacuum lines, a failure of the sensor, or a failure of the valve itself. Since the valve is exposed to the heat of the exhaust system, it is prone to jamming from carbon buildup and destruction of the vacuum diaphragm from heat.
egr valve used to reduce emmisions. the valve will open at driving speeds to reburn exaust gases. when one fails it will usually be in the open position thus the engine will run rough at Idell.
The 2004 Dodge Durango EGR valve can be found on the firewall in the engine compartment. The EGR valve will be on the passenger side of the firewall.
The EGr valve can be difrent and is in difrent locations on the various engines
Check the EGR valve. It sounds like your EGR valve is staying open. An EGR valve that is open at idle will cause a car to stall. An EGR should be closed at idle and open when you are driving around.
Yes, if the valve is bad. With the car idling, move the EGR valve diaphragm with your fingers. The engine should quit or want to quit. If it doesn't do this, it could be plugged up. Remove the EGR valve and clean any carbon deposits in the valve and also do the same on the engine side where the EGR valve is connected. If the EGR has never been removed before, it will probably have carbon buildup.
replace the egr valve the one you have is not good
Carbon build up.
Does a 2000 pontiac gran am 4 cyl. Have an egr valve all that parts stores have is a gasket. Gm says it does not have one. Car shakes and shimmies when you stop at an intersection which everyone says check the EGR valve
Test it with a vacuum hand pump.
Realley need to no what your working on and the year.
The EGR valve is located at the front of the h22a4 engine. The EGR valve is right beside of the front of the EGR valve.
Check your EGR valve Check EGR valve
If it's stuck in the completely open position, it can.
Yes. Carbon deposits in the EGR valve can cause it to stick open a bit and cause a rough idle. If it is bad enough, the engine will stall out when you slow to a stop.
Yes, the EGR valve, or port EGR
Check your EGR valve
check your egr valve or throttle positioning sensor
