My name is Jon and unfortunately I was driven to this forum do to what seems to be a common problem with the EGR sensor for my 2005 300 touring. This is my wife's car that I try to keep in as pristine condition as possible. It seems that the people in the forum are rather knowledgeable, so I will definately appreciate the information I get. Thanks. FYI: I ordered the EGR Valve and am going to attempt to replace (with a mechanic friend's help) so any tips would be appreciated.
