Hi. rough idling and service engine light continues to go on. According to code given, the EGR Valve is the cause. Replaced the valve. Idle is the same and code still says the valve is bad. Any suggestions?[img:04d9f3a4fe]http://www.2carpros.com/forum/automotive_pictures/78970_Picture_028_1.jpg[/img:04d9f3a4fe]
