Hey everyone I've got a 91 excsb 4x4 that I'm building a motor for I'm switching from the original 1-wire Oxygen sensor to a Heated 3-wire O2 sensor and i will be running long tube headers to a Y-pipe.
My question is should I drill the hole for my o2 sensor bung on the drivers side header which is where I'm pretty sure the factory O2 was located or do I go down to the Y-pipe when both sides come together so It can read off both banks?
Thanks for your help
