Fudgesicles! Got the NOX down to pass, HC was still under limit, but the CO is still high.

I threw in a new O2 sensor today, as the old one was looking pretty gunked up, plus I reset the timing as I had it a bit over-advanced (like at 12 BTDC instead of 7 which is spec). After I plugged the vac leaks I'd found and did the sensor, it liked to ping lightly on the freeway at moderate load, which one of my old Raiders did when I had a touch too much advance.

But that all wasn't the fun part. Before I even got to emissions, my battery hold-down decided to come undone, allowing the battery to slide towards the engine, melting part of the positive cable and severing it, while subsequently starting a real live fire! I put it out and just sort of rested the cable on its other half and it sort of stuck there. I figured since I was a block from emissions, I'd just go through anyway. At least I made it home.

Here are today's numbers:

HC....2.48/3.00 = pass

CO....46.96/25 = fail

NOX...3.17/4.5 = pass

Sigh...help?? Suggestions? Push off cliff?
