No problem Steve.

Personally I think I should have at least tried to run a check (connect, disconnect, check voltages (?) ) on the old O2 sensor. Given that it's pre cat, even with the huge leaks on muffler, the amount of exhaust and flow should have been sufficient for it to "sniff". .... if it was working. Of course I don't have a CO tester and the bung on J pipe is well rusted in place. I ain't touchin' that!

Neil.
