How many 02 sensors does a 95 camaro z28 have?

A 1995 Camaro Z28 typically has four oxygen sensors: two upstream (pre-catalytic converter) and two downstream (post-catalytic converter). The upstream sensors monitor the air-fuel mixture, while the downstream sensors check the efficiency of the catalytic converters. However, it's always a good idea to verify specific configurations for any modifications or variations in the vehicle.
