Why would a 95 Camry stall at stops but once restarted run fine?
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.
Would a erg valve cause a dead battery?
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 ,
Would a clogged EGR valve cause a loss of power and poor gas mileage on a 1983 Nissan pickup?
Yes, most definitely.
How does the car know the EGR valve is bad?
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.
Would a bad EGR valve on a 1987 Volvo 240 DL have any effect on passing the NOx for emissions?
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.

Would a faulty egr valve cause your car to jerk?
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.
How do you replace the EGR valve on a 1996 Isuzu Trooper?
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.
How do you replace an EGR valve on a 2001 Ford Focus with DOHC engine?
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.
What is the cause and corrective action required for pieces of carbon getting caught in the EGR valve on a Chevy S-10 with a 43 Engine?
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.
