i passed emissions. I ran super and put 2 bottles of HEET in it.

Everything was well in spec except the NOx which was near the brink. I wonder if the alcohol raised it as someon here suggested. The fuel in CT is MTBE this time of year, so maybe I didn't need any alcohol. I might skip it next time since the NOx was high.

I recently tuned the car, so caps/rotor/wires filter etc was all new.

In CT they run pre-OBDII cars on rollers, I assume there might be a load on them.

I was the first person in the morning to get tested and the test station had to be started up. I ran the car hard on the highway to warm it up, but I had the car idling for 1/2 hour before their equipment was calibrated and ready. I am not sure how hot the cat gets when sitting idling for some time.
