As of the last couple of months my CEL has been on, and I've had it checked several times...every time it's been diagnosed as "Insufficient EGR Flow." Initially I thought it might be the valve itself and replaced it...but that wasn't it and after talking to some people they said that it was probably a plugged EGR tube and wasn't worth the hassle. I was wondering if anyone knew if this actually was worth fixing and if so how laborous of a task it was.
