94CutlassSLCoupe Posted August 15, 2007 Report Share Posted August 15, 2007 This is for my sister's car, and I'm not about to drive to Milwaukee to fix it. Anyways, here's the story. My sister takes her 94 Cutlass Supreme 3100 to the emissions station for the bi-annual test. The car failed with a 2.66 NOx reading on a 2.00 max allowable. All other scores were very low compared to what they allow. It has had a recent tuneup, and she has since installed a new air filter. The car has always had trouble with its digital EGR so she purchased a new one off of ebay at a very low price to install...($60 shipped) SO, what i need is some pictures of this process for a How-To so she can handle swapping out her EGR and cleaning the passage. Any good pictures would be a great help. Her car needs to be run through again within about the next two weeks. Thanks for any help! Quote Link to comment Share on other sites More sharing options...
Brian P Posted August 15, 2007 Report Share Posted August 15, 2007 I don't have any photos right at this moment, but tell her once the EGR is off, to clean out the hole that the EGR pipe is NOT attached to. She's also better off to remove the throttle body, where the opposite side of the EGR port can be cleaned too (plus the pieces of carbon etc can be removed instead of sucked thru the engine).

Brian P Posted August 16, 2007 Report Share Posted August 16, 2007 http://i174.photobucket.com/albums/w86/riven2129/project/egr6.jpg closest I can find on a quick search. Tell her to clean the hole that's part of that C-shaped indent Quote Link to comment Share on other sites More sharing options...
MonteCarloChick Posted August 16, 2007 Report Share Posted August 16, 2007 When she removes the TB, she can see where it's clogged. It really isn't that hard.. Quote Link to comment Share on other sites More sharing options...
