I had an issue with the EGR valve. My check engine light came on so I went to Advance Auto to have a free diagnostic check done. The EGR valve message came up. The associate sold me a can of Seafoam, I think its 8 oz., he told me to pour the entire can into my gas tank with a full tank of gas and that would clean the valve and the engine light would go away. It didnt go away until a week later because it took the entire contents in my tank to go through the EGR valve before it was totally cleaned. IT WORKED GREAT! You have to do this and you will be set. Let me know in a week when it is fixed.
