Is it possible to replace an EGR valve?
While EGR valves can be complex, as long as you keep your current part until you’re ready to replace it, you should be able to get a replacement part that will work just like new. YourMechanic can install or replace an EGR valve for you. The most popular service booked by readers of this article is Exhaust Gas Recirculation/EGR Valve Replacement.
What are the symptoms of a bad EGR valve?
A rough idle upon starting the engine (that is, when the engine is cold) and sometimes at a stop light or while looking for a spot in a parking lot (that is, at low engine speeds in a warmed-up engine). Stalling when the engine idles. Increase in fuel consumption.
What are the pros and cons of EGR?
Cons of an EGR Valve. When the EGR valve goes bad, it must be replaced. Unlike some emissions control devices that can go bad without affecting the drivability of the car or truck, a bad EGR valve can really affect the engine’s performance or even cause it to stop running altogether.
How to clean a blockage in an EGR battery?
You will need to clean the EGR valve of the blockage using the following steps: 1 Disconnect battery 2 Remove sensors or clips 3 Loosen bolts holding the EGR valve 4 Use a EGR or Carburetor Cleaner to spray the valve and hoses 5 Reconnect the battery

How does exhaust gas recirculation ( EGR ) valve work?
EGR valves work by creating a small and calibrated “leak†between the exhaust and intake manifolds. This passageway allows some of the exhaust to be circulated back into the engine; however, this amount must be closely controlled by the EGR valve as a large leak leads to significant reductions in engine performance and drivability.
