Funny you should mention that. I decided to perform some testing on my emissions equipment on my car to make sure everything was performing as it should.
According to the Hanes manual, the '94 and newer CIvics had an O2 sensor.
Mine is a '93 and doesn't have one.
I replaced the O2 sensor a couple of years ago with a Bosch unit because it supposedly reduces emissions better than a stock part.
I wonder if I can install an O2 heater without buying one for a ' 94.
