i installed a header on my base RSX and now i have 2 codes. It has to do with the o2 sensor. I tried to do a ghetto sim but it didnt work. When you do those ghetto sims which one has to be rigged? The first o2 sensor or the bottom o2 sensor? When i did the ghetto sim i put it on the bottom o2 sensor but the code never went away. I reset my ECU and it came back 2 mins later. How do i get it fixed?
