What is your question?
Hello. I just took my 1994 Chrysler New Yorker to get e-checked, and it failed on NO (NOx). HC and CO were within specification. The reading for NO was 830.2 @ppm and the spec is 796.0 @ppm. The Vehicle was at normal operating temperature. This vehicle was checked last year, and passed. Just curious for some suggestions on where to start, to fix this issue, for I have been out of the car business for a long time.

Thank you for your reply. I do have an EGR valve. Also, there are a total of 3 converters on this car. ANy more insight? Cooling system seems to be working properly. Hmm..this car has an EGR solenoid. What could I do personally, to see if the EGR solenoid is opening up the EGR. If I put direct vacuum to the EGR itself, the EGR opens and closes, etc, so I would have to assume that the EGR itself, functions, but I am wondering if the EGR solenoid is not.
