FIY, the F&B Stage I passed the Ontario Drive Clean Program.
I left the MP cam/valve train components/rockers/headers, K&N
open air cleaner, F&B tb, Autolite 3924 plugs on. I removed the
180 tstat, Redline water wetter and '96 MP computer. I was
too concern with the engine performance parts since they are
CARB approved.
Results:
40 km/hr (about 25 mi/hr)
Limit Reading Result
HC ppm 58 57 PASS
CO% 0.32 0.13 PASS
NO ppm 0615 48 PASS
I asked about my high HC ppm reading and the owner said that
timing, vacuum leaks and/or something causing a rich condition
are usually the main causes. He said that the MP cam might
be affecting the timing although everything is running well.
