Even a good EGR valve may cause an engine to stall in hot weather.
Start and stall out, possibly. Not start at all, not likely.
I would not expect a valve cover leak to cause a car to stall. A valve cover leak can fill the spark plug area with oil which can cause rough running.
Yes if the vehicle is equiped with coil/coils and will cause missfire, oil there means your valve cover gasket is shot and if this is the case the plugs maybe be fouled. But generally you should seek diagnosis from a professional the vehicle may have other issues depending on the type of stall
no it will not...
Try cleaning the EGR valve.
Check the Park Avenue EGR valve for a clog. A clogged valve can cause a rough idle and stall at a light.
No
If the valves are incorrectly adjusted it will hurt performance.
a bad idle sensor control valve to start with or your egr valve has a vaccum leak
Numerous things could cause the Nissan Altima to stall. One such thing is the idle control valve, also the exhaust system could cause the engine to stall.
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.
