i think your lambda sensor is your O2 sensor which is located in the exhaust manifold. look at the heat shield for the manifold. on the firewall side, you will see a wire coming out from underneath it. this is connected to the O2 sensor.

thanks for your answer, but my problem is not exacltly this.
the fact is that i have bought this car a month ago and the last propietary converted the inyection fuel sistem to carburator sistem and also he changed the exhaust sistem for a Performance Exhaust Headers and it haven't the lambda sensor thread.
My intention is to put the original injection system an i don't know where i can put the sensor thread.

the factory sensor is located just above the flange where the manifold joins the exhaust pipe. this is in the "2 pipe" section.

If the header has a place for the lamba (oxygen) sensor, then is toward the rear, where the 2 pipes go into 1.
I have also seen them in the header tube for the number 1 cylinder, but I am sure you would see it if it was there.

If you do not have one, then you can have an exhaust shop weld in a 'bung' for a lambda sensor. That is something common around here. Where are you located? If you cannot get one I could find you one here.

If it is not the one that goes to the negative terminal of the coil, then it may not be used.
The one that goes to the negative terminal usually does not have a plastic connector, only a metal one.
