Any thoughts on my failing emissions results?
idle hc: 440ppm (220 limit)
CO% idle: 00.01 (1.20)
2,500 rpm HC 492 (220)
CO% 2,500 rpm 00.02 (1.20)
Is this a misfire? I have new MAF, plugs, O2 sensor, no codes etc. Smelled nice and clean when I left the house but after leaving the test it stank of gas.

was the car fully warmed up before the test?
the coolant temp sensor might be worth replacing, its cheap enough.
also run some techron through and on the next tank use high octane gas before the test.
