      Lean mix gives high NOx, where's that in his readout?

      advance the timing to 10 btdc. Late timing will contribute to incomplete combustion.
      Late timing also gives high NOx. . .

        We do not test for NOx in the state of New Jersey. Just gotta pass visual emissions, and HC.

          yep, no NOx checks anymore since they did away with the dyno roller thing. Its just an idle and high idle (like 2000 rpm) check. We get a printout with HC, CO and CO2 figures only. If it still has the field for NOx, it usually says N/A.

            Sorry for the delay, been trying to get stuff done on the car and was having problems getting on here with my password. I finally got a chance to put a new set of wires on, the timing was advanced to 10btdc from 8, and my Dad tossed from Marvel Mystery oil in 2 different fillups. The car passed though I didn't get a print out this time. The HC numbers dropped to about 109ppm at idle so a big difference there. Considering the change from the first to the second run I'm guessing there was something going on with the wires, though the timing being off probably didn't help any. Next big problem I'm looking at is my the pass hinges on my tudor got bent so that should be fun. Thanks for the help everyone.

              you can get readouts from the njinspection website. All you need to do is supply them with the vin and you'll get the most current readout
