Hi,
I am consistently getting this code from my 98 Mercury mystique. I had this code once before(several months ago), and the autoshop said the egr passage was blocked with carbon, and it was so bad that they have to take the tube out to drill out the carbon deposits. Several months later, the problem returned. Now I am wondering what I should do. I am wondering if this is something that is easy to do for myself, since I don't know much about cars. I will really appreciate if someone can post the instructions (photos too) for fixing the problem. Thanks.
