well, that was pertinentThat's a Rip off! Those guys are ripping you off ! I just finished replacing my EGR Valve on my 2003 Mazda Protege 5 and it was the biggest pain in the neck you could ever imagine. Its really hard to get to because when you put the 3/8 Rachet on thter the Ratchet hits the Motor Mount and you cant put it on straight so i just used a 1/4 Ratchet and a 12mm socket and that did the trick
apparently, the way to go per the "other" forumHave you tried cleaning it?
