Options20002001 Posted July 28, 2005 Share Posted July 28, 2005 My 93 ES300 with about 100k miles failed inspection due to high HC and NOx. Emissions were higher at lower speed (~15 mph). Last year there was nothing unusual, passed inspection and I don't recall any major (or even minor) repairs in this duration. The car runs fine...no hesitation or misses. However, I do feel that the mileage has decreased in the last year. Also, just before testing, I had noticed my PS pump whining (turned out to be a leak) and had the injectors cleaned. Could this have caused a failed emissions test? What could be the culprit(s)? Any easy test? Where should I start? Thanks. Options Quote Link to comment Share on other sites More sharing options...
SKperformance Posted July 28, 2005 Share Posted July 28, 2005 Are you sure you cat was heated up properly before the test? Quote Link to comment Share on other sites More sharing options...
