Runs great but seems to be a bit on the 'rich' side. Usually fails NOX at inspection time, tail pipe is sooty, MPG isn't quite what it should be. Mileage of engine is unknown as I'm not sure if its the original engine. The van shows 110K. Engine uses only the slightest bit of oil between changes. There are no vacuum leaks and the condition exists even with a new oxygen sensor. On a carbed engine, I'd know what to look for, but with FI and computer I'm a bit lost. Any common causes for this? Suggestions? Sage words of advice? Last edited by Satilite73; 04/07/12 12:26 AM. John The dream is dead, long live the dream.......😥
