Hey all, new problem with idle stalls. Well same problem. I have replaced the idle bypass valve, throttle position sensor, and egr valve. After egr the idle became even worse climbing up to around 2k rpm then dropping off and stalling out, and is now running very rough. Any thoughts on what I am missing here?
