STYES Posted February 18, 2005 Report Share Posted February 18, 2005 From my experiences, cleaning the EGR valve and passage is not necessary on a car that is driven hard at times, especially when the WOT proceudre is frequently used. The problem I have is that my car is the only basis I have for this. All others I've seen sure could use a good cleaning, but I am pretty sure these cars are never driven hard. Please share your thoughts on this one. Thanks! Link to comment Share on other sites More sharing options...
