Yes
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.
geo metro had a problem with the egr valve going bad causing the # 3 exhaust valve to burn, which could cause a lack of power in the engine performance. if this exhaust valve was burnt due to a faulty egr valve the new egr valve could have gotten clogged again causing a check engine light to reappear.
Could be the PCV valve is faulty.. Checking mine tomorrow for the same reason!
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.
If the valve timing is correct and there are no damaged engine parts (or weak/faulty valve springs) that should not happen, yet however if the engine is "over-revved" the valves could "float" which is not normal operation. (If the engine is an interference engine there may possibly be engine damage.) That is normal and it is called valve overlap.
Blocked heater core, faulty heater valve, disconnected connection to the heater valve.
One possible cause for a 1995 Dodge Avenger stalling when shifted into reverse could be a faulty idle air control valve. This component is responsible for regulating the engine's idle speed, so if it is malfunctioning, the engine could stall when the transmission is engaged in reverse. It is recommended to have the idle air control valve inspected and potentially replaced to address this issue.
No. The purge valve is part of the EVAP system. The EVAP system reclaims and burns the gasoline fumes from the fuel tank and prevents the fumes from escaping into the atmosphere. A faulty purge valve would cause the "check engine" to illuminate but not cause the engine of the vehicle to "die".
A faulty pump, a faulty switch, a faulty release valve on the drain pipe.
Could be--valve not closing completely
A faulty PCV valve can certainly cause idling problems, especially after the engine has warmed.
EGR valve is Exhaust Gas Recirculation valve that recirculates exhaust gas through the intake manifold to improve emissions. Typically this valve has a electric connector and harness that is computer controlled. If this valve is faulty, it will cause a check engine light to appear, or a service engine light. In some cases, it will make the vehicle run roughly. Does that help you?
