Funny thing about the EGR. I had a CEL come on for the EGR. I purchased a cheap brand that had really good reviews. I cleared the code and the CEL did not come back on. A few weeks later I hit a washboard section on a county road near my house. The CEL came on for the EGR. I went home and cleared the code and went back through the washboard section and it turned on again. Now I know there is always coincidence possibility, but not twice in a row. I installed a Standard Motor EGR and went back to the washboard and it did not come on. When I changed the EGR I noticed that the spring was much weaker on the cheaper EGR, even though they were both new. Like CT said, a weak spring can cause problems. It may not close all the way or open on rough roads.
