    The short answer to your question is yes. The exhaust gas recirculation (EGR) valve introduces a measured amount of exhaust gases into your intake manifold to get re-burned. This helps lower engine temperature and prevent harmful emissions. But, the valve can fail and stick either open or closed. When the valve sticks open it may prevent your engine from starting. Other symptoms of a stuck-open (EGR) valve include rough idle and stalling. If you're experiencing any of these, you probably have some sort of EGR problem.


    The EGR valve is intended to permit the progression of exhaust gases into the engine in controlled amounts. At the point when you turn over the motor, the valve wakes up and holds in a shut position, hindering the progression of exhaust gases. When the motor gets to working temperature and speed expands, the valve, either through the vacuum or electronic control will steadily open, permitting consumed exhaust gases to enter and consolidate with the air-fuel combination inside the ignition chamber. At the point when the EGR valve is stopped up or messy, as they are inclined to, it may not work appropriately, causing poor fuel mileage, or radiating a solid smell of fuel because of overabundant hydrocarbons. I would suggest having an expert take a look at the car to see if it needs to be replaced or just needs a good cleaning.
