Re: idle problems
If the EGR valve is stuck, I've heard you can clean it out and reuse it for a while. This is a good way of making sure if the problem is fixed.
The EGR is a ball valve, a ball inside a cylinder which when push one way will allow air/fluid to flow through, but if the ball is pushed/pulled the other way, it will block the opening.
