Poor performance, poor economy, rough idle, lean burn causing valve or piston problems...
Extra loud engine sounds.
High idle speed.
Lean burn condition that could result in engine damage.
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.
no a egr valve would not make a dead battery. a bad alternator or maybe a bad connection post to battery would make it die ,
Yes, most definitely.
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.
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.
* Remove the air intake duct from the throttle body and air filter housing * Position the hoses and wiring harness aside to access the EGR valve * Disconnect the EGR pipe * Remove the EGR valve mounting fasteners * Remove the EGR valve and gasket from the manifold.Discard the gasket * Using a gasket scraper clean the EGR valve mounting surface
* Remove the air intake duct from the throttle body and air filter housing * Position the hoses and wiring harness aside to access the EGR valve * Disconnect the EGR pipe * Remove the EGR valve mounting fasteners * Remove the EGR valve and gasket from the manifold.Discard the gasket * Using a gasket scraper clean the EGR valve mounting surface
Would this cause the car not to start If the EGR VALVE is bad
* Remove the air intake duct from the throttle body and air filter housing * Detach the vacuum line from the EGR valve.Disconnect the EGR pipe nut * Remove the EGR valve mounting fasteners * Remove the EGR valve and gasket from the manifold.Discard the gasket * With a wire wheel buff the exhaust deposits from the EGR valve mounting surface on the manifold
no gasket sealant needed. Just original gasket is fine.
Yes, the EGR valve, or port EGR

A faulty or clogged egr valve can cause an engine to run rough. If stuck or clogged the valve can be cleaned after removal with carburetor cleaner.
OK here it goes: The EGR valve is a cylindrical unit above the engine. It would be behind the throttle body. It will have a cable connected to it. Unplug the cable. There two bolts. Simply remove. An that is all there is to it. Simply put the new EGR valve in its place, screw in the bolts and reconnect the cable. Make sure to see a gasket. The gasket can stick to either the EGR valve or the throttle body. It does come off easily but since it is metallic, it looks like it part of the throttle/egr valve. Make sure to install the new EGR valve with a gasket. I have read that using the old one is OK.
Removal Remove the air cleaner outlet tube. Disconnect the mass air flow (MAF) sensor electrical connector. Disconnect the breather pipe. Remove the air cleaner. Fully loosen the exhaust gas recirculation (EGR) valve to exhaust manifold tube nut from the bottom of the EGR valve. Disconnect the vacuum line from the top of the EGR valve. Remove the EGR valve. Remove and discard the EGR valve gasket. Installation NOTE: Use a new EGR valve gasket when installing the EGR valve. To install, reverse the removal procedure.
an EGR valve gasket is available that has a screen to block the carbon. They cost $5.69 at the autoparts store in my city.
