The EGR valve may stick open, causing a rough idle and/or the Check Engine Light to illuminate.

    Chck engine light came on recently. After extensive research online I believe the egr valve is causing this issue as well. The car when in park or sitting at a stop sign/red light rpm will jump slightly sometimes and be very rough and jump a lot other times
