I had a question about my oxygen sensor that I have a feeling you would have the answer to. First off, this summer I swapped a b16 in my teg. I love it, but I have had the check engine light on since then. It is for my oxygen sensor. Right now I have a DC header for a 92-93 teg when my teg is a 90. Don’t ask me why, it was the stupid ass shop that decided to do it that way. I really didn’t care at the time, so I let them go ahead. Anyway, do I have to run two oxygen sensors up by the radiator or can I figure something out with the one down by the cat? Is this cutting performance only running one sensor? I know it is killing my gas mileage. Any advice would be great.
p.s. what adaptor do I need for my electric oil pressure sender?
Thanks a ton!
