just wondering how do you test the o2 sensor on an eb? i took it out from the exhaust manifold, it was black with carbon, tapped it nothing came out of it. so i put it back in. then i disconnected it at the connector and started the car, nothing seemed to be different, i took it for a quick drive and it was all normal, the fuel consumption didnt change the car idled fine, no differance. could this mean something? is there a proper way of testing this sensor?

most certain way is to put it on a dyno with a A/F sensor. Run it and then disconnect the O2 sensor. The A/F mix should go off the scale. If it is off the scale BEFORE you disconnect it you certainly may already have a problem.
EA through to EL all the same manifold, and same oxy sensor, well changed slightly got smaller with technology, but same none the less, as Casper said, you need to measure whats coming outthe exhaust really, unless what I posted is not hapening at all, but works fine in your dads car, then you either have a wiring problem or oxy problem, depends on the results.
I did put something here, but it vanshied, I think
