91 Acura Integra - High NOx - Failed emissions test - NJ
My 91 acura Integra LS failed the emission test a second time for high
NOx. Could the gurus please provide some input on what I should be checking? Here are the details. Test 1: NOx - 1984 HC - 91 CO% - .34 CO2% - 14.3 O2% - .6 After this test, my mechanic replaced the Catalytic convertor. The second test results we Test 2: NOx - 1367 HC - 10 CO% - 0.00 CO2% - 13.2 O2% - .9 So, the NOx did drop but not enough to pass the test. (The pass level of NOx in NJ is 1088) Any recommendations on what could be the big culprit? Thanks in advance. |
