Leon (and others... :-) ) can you give me an opinion? Today i have measured the tension of the O2 sensor. With warm engine, at idle, are indicated 0 volt. With engine to 3000 rpm, the sensor marks 0,50/0,60 volts, sometimes
0,30/0,40. When the engine comes down at idle the value is 0 for a moment, then go up to approximately 0,40/0,50 for another moment, and finally comes down to 0. Accelerating repeatedly, the value of the O2 sensor go up approximately to 0,50/0,60 volt, but it never doesn't go up to 1,00 volt... Moreover, there is a little lag when i press the accelerator at idle... What do you say?... I replace? Unfortunately I don't find in aftermarket the NTK O2 sensor for my '91... Have any idea to buy an OEM O2 sensor, without spendig 300 euros?! (Is the cost here, in Italy...) Thanks, Stefano- posted
