Yes, it would. I have an '01 Solara, and when I took it to the dealership to see why my check engine light was on, after they scanned it, they told me that it was due to a bad egr valve.
Start the engine, and spray a little carb cleaner around and on the EGR valve. If the engine changes sound are idles up are down then the valve is bad.
A bad EGR valve should not cause the engine to not start. There is most likely another problem that is causing the engine to not start.
A bad EGR valve in a 2000 Saturn can have several symptoms. The EGR valve can cause misfires, the valve can cause vacuum leak style problems. There could also be an engine knock.
It can.
If the egr valve was stuck open, the engine wouldn't idle. If the egr valve was stuck closed you may hear excessive pinging (spark knock) and in most vehicles, the check engine light would illuminate.
Never heard of an EGR pump and need to know what year, make, model, engine and what valve you are looking for.
Even a good EGR valve may cause an engine to stall in hot weather.
Yes it can if it is bad you will see the cel
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 engine light on
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.
