Hyundai XG350 ProblemsRough Idle Due to Faulty EGR Switching Valve
A defective exhaust gas recirculation (EGR) switching valve may cause an intermittent rough or unstable idle engine.
If the Check Engine Light illuminates, indicating a problem with the front oxygen sensor, but the sensor tests okay, reprogramming the engine's control computer should fix the problem. Then, the Check Engine Light will no longer falsely illuminate and the acceleration, particularly from a stopped position, will be smoother.
