If the egr valve is stuck OPEN - the Engine will run Very rough & idle bad - or not idle @ all-if the egr valve is starting 2 stick IT WILL TURN ON THE CHECK engine light-Sometimes U can take the valve off & clean them with a GOOD carb cleaner.

AN EGR (Exhaust Gas Reclaimer) sensor monitors the EGR and sends a signal to the ECM (Engine Control Module) letting the ECM know if the EGR is open or closed or anywhere between.
