sabot Posted March 19, 2004 Share Posted March 19, 2004 I own a 1993 sc400 and failed emissions on inspection. The NOx was a little high. I think the egr valve needs to be replaced. Where is it located and where do I get one. Thanks Chick Quote Link to comment Share on other sites More sharing options...
