The EGR (exhaust gas recirculation) valve is a crucial component on a Ford vehicle. The EGR valve regulates the fuel intake, ensuring that your vehicle runs efficiently and smoothly. The valve works by recirculating some of the engines exhaust gasses back into the engine cylinders, thus creating less pressure. When you notice the Ford beginning to idle roughly, it is time to check the EGR valve to see if it is damaged or clogged.

Place the Ford in “Park” and engage the emergency brake. Turn the ignition key to start the vehicle and allow the Ford to warm up for fifteen minutes.
Locate the EGR valve under the hood of the Ford. Look on the engine intake manifold for a small, circular metal valve. Refer to the owner’s manual for a diagram, if needed.
Identify the plunger mechanism within the valve. The plunger is located on the outside of the valve, and is the part of the valve controlling the exhaust direction.
Visually analyse the valve’s plunger mechanism function. Have someone assist in the process and ask this person to rev the engine; make sure the valve plunger opens and closes in rapid successions. Failure of the valve to open and close quickly means the valve is faulty or clogged and needs to be replaced or cleaned immediately.
