the gold2 Posted November 22, 2010 Report Share Posted November 22, 2010 Hello, a quick question. The 92 Eldorado has two EGR stack pipes inside the throttle body. One toward the back is rigid and does not move when handled. The one toward the front of the car does rotate when handled and sits non-fixated(handled via the opened throttle plates). That one seems to have a 'collar' at it's base. Normal? I'm curoius now because recently I cleaned the area and just took this observation for granted. Thank you !!
