GOOD NEWS!
I have passed emissions. If you see my previous post how I barely failed, I checked my plugs to ensure they weren't fouled/dirty (which they weren't). It led me to the conclusion that the only reason I failed was that I brought the car while it was cold (a barely 5/10 minute drive to the emissions station).
So this morning, I let the car warm up for about 30minutes and reach operating temperature so that the Hydra would be aiming for that 14.7:1 AFR. It worked.
My new results on a sniffer test were as follows:
Hydrocarbons (HC): 158ppm on a limit of 188ppm PASS
Carbon Monoxide (CO): 0.61% on a limit of 1.00% PASS
Nitrogen Oxides (NOx): 1925ppm on a limit of 2188ppm PASS
So tomorrow I'll get to the DMV and get her registered and begin my journey of fixing her up. I'll start a build/progress thread soon.
