How can I tell if my EGR valve is stuck open?
Open Position: Rough idling and problems with acceleration are the two most common indicators that the EGR valve is stuck open. The truck might also stall excessively. When the EGR valve is stuck open, all of the exhaust gas cycle back into the chamber, meaning there’s not enough oxygen for a combustion to take place.
