Questions from a newbie

[rr]

Sounds like the plugs fouled and miss-fired. Then seeing all that O2, the
ECM was adding fuel. Now that the VE is closer, is the O2 reading
making any sense?

Search net for +O2 +sensor +test, there is a paper or two out there
detailing testing with a propane torch & dvm.

Dunno why but the INT and BLM values don't seem to jive with what's actually going on. I've read tuning tips multiple times now and lately I've been trying to understand the anht_hac.
