* Reduced engine power: The EGR valve helps to recirculate exhaust gases back into the engine, which can help to improve fuel efficiency and reduce emissions. If the EGR valve is not working properly, it can cause the engine to run rich, which can lead to a loss of power.
* Stalling: A faulty EGR valve can also cause the engine to stall. This is because the valve can allow too much exhaust gas to be recirculated back into the engine, which can cause the engine to run too lean.
* Check engine light: A faulty EGR valve can also cause the check engine light to come on. This is because the valve is monitored by the engine control unit (ECU), which will set a trouble code if it detects a problem.
If you are experiencing any of these problems, it is important to have your car checked by a qualified mechanic. They will be able to diagnose the problem and replace the EGR valve if necessary.
