thanks everyone for the amazing help! Ryguy, how do i bypass the BPT? The guy who usually smogs me can be lax on the visual (he let me pass vis with no name headers, even after pointing them out to me
lol), so i think he might overlook this too. and what did your levels change to after the bypass? did CO and HC raise, but NO lowered? or did the NO just lower? could the NO levels have anything to do with a bad Cat either? im not sure if it is bad, but i was going to swap it with a known good one and try that, but that might take a bit so the bypass would be a quicker fix if it works
