Click the link above. There are some good pictures in it. After you take the EGR off, clean it and set it aside. Now, back in the area you removed the EGR from are two holes. The larger one is the hole you plug and the other you shoot the cleaner into.
You need the car running to do this, you may need a partner to help. A lot of people say they don't, but I do, mine stalls quick. After you button it all back up, disconnect the negative terminal on the battery to clear the codes.
