Could any one help me with my EGR valve? Is there any thing I should know or try before I start thowing parts at it. She runs great but this check engine light is annoying me.

Change the EGR valve simple to do

by the way what engine you have?

2.3 liter. What about the egr sending unit? I'm under the impression that that is more likely to go first.
