Good news/Bad news
Good news: I passed VA emissions. I ended up changing the O2 sensor, plugs, wires, distributor cap and rotor, and a bottle of "Guaranteed to Pass". I feel like I'm getting +5 mpg. When I went to change the O2 sensor, I found it unplugged. I'm not sure when it happened, but since it was 12yrs old and I already had a new one, I changed it.
OLD Numbers
25MPH Limit Reading HC ppm 148 39 CO% 1.54 0.02 NO ppm 934 123
Bad news: When changing the distributor cap, I broke one of the bolts. It was deep enough where I could not cut a notch and back it out. I was unsuccessful trying to drill the bolt out. I had a bad angle and could not drill straight. I ended up mangling the flange on the distributor. In the end, I have a bolt on one side and a tie- tie on the other. It's not 100% tight, but pretty close. What could happen?
Thanks for all the suggestions.
