Re: help with Obd0 civic vtec (bobbymoon)
the placement isn't particularly important. The most important thing is that the ecu has 2 sensors to monitor.
In a perfect world, you would have a 4-2-1 header, and the o2 sensors would be plumbed on each of the 2 section of the 4-2-1 header, so you are getting 2 cylinders per o2 sensor.
In reality, a lot of people just run them somewhere on the single exhaust pipe, after all the exhaust gas merges, but before the cat. it should work fine either way.
