So I can't find the o2 sensor anywhere on the exhaust. I've searched and searched and never came up with a diagram, picture, or anything. Car smells like gas at idle and fuel mileage is worse than my carbureated formula. can someone hit me with an assist on this? Thanks.

 

Driver's side exhaust manifold. Get it out from underhood near the steering shaft.

 

Thanks. Im new to working on older cars. Would this o2s wave form have the same rich to lean oscilliation as a newer car does?

 

Yes.


.1v lean - .9v rich, 100ms wave. These O2's do not have a heater so they take a while to start reporting properly.
