Hey guys,
Sorry to take so long to get back, I did go by Auto Zone and have my code read, the result was a defective EGR valve. The salesman 'suggested' that I buy a new valve, at $183, I declined telling him that my bro-in-law is a mechanic and that I would get with him about purchasing a new part.

After reading thru several posts on the same topic, I'm curious, does a "defective valve" mean that I need to replace my current valve or can I simply try cleaning my existing valve?

Any advice I would greatly appreciated.
