The EGR is on the back half of the motor. pull the throttlebody off and you can get to it. There is one electrical connector and 2 fuel lines, also an exhaust line. everything will come off easily, except for the exhaust line. the part will cost between $250 and $500. dont clean it up, just replace it. its a lot of work to do to just find out that its really bad.
