OBD II Emissions and O2 Sensors
OBD II Emissions and O2 Sensors
I have a '97 Z28 and live in MA. I'm going to get some MAC mids and can't decide between a catted y or an ory. I know that '97 and up vehicles get tested with the OBD II and not the sniffer here in MA. If I got an ory with O2 sims, do you guys think I'd pass a straight OBD II test (not worried about visual?)
