Is it easy replacing O2 sensors
You will only have "front" O2 sensors on a 1993, rear O2 sensor(behind cat converters) were not used until 1995 and up
Drivers side, left?, shouldn't be to hard to unscrew from under the truck.
You can't use a regular box wrench or a socket because of the wires
Brake line style wrenches work, and they do sell O2 sensor wrenches
I think its a 7/8"
Now the connector can be a bit of a b*tch, if its up behind the engine, but unscrew the O2 sensor first then reach in from above and pull the sensor up to top of the engine and you should see the connector appear, swap sensors and lower sensor back down
Spin new sensor around so wires will unspin as you install it
If you have any use anti-seize on the threads of new sensor
