91 need secondary o2. Sensors?
Hey guys. We are getting ready to turbo our 91 celsior. I have read a lot of people have removed the secondary o2 sensors. Have any of you guys done it ? Any potential issues? We will be installing an ecu but just curious in the mean time

no one here has probably done this as most folks here do not do drastic engine upgrades like adding a turbo. I assume you would omit the catalytic converters anyway rendering a secondary O2 useless in the first place. check out lextreme.com for more aftermarket support.
if you will be running a stand alone aftermarket ECU, then just program it to not look for secondary O2s. they are only required by the factory ECU on cars with cats.
