New bad O2 or something else.
Installed heated 4 wire O2 over the winter and took vette out for first time with the new O2 and did some data login, noticed the O2 reading are not fluctuating as they should be, so did I get a bad sensor or something else I should look at. this is with a 7727 ecm, link to log.
