one more problem with 02 , the old car had a 1 wire 02 but is not really true (electronics) the casing is a wire that ground to the rusty old intake manifold
so making up a wire from engine block aluminum head to the manifold exhaust some way can make 02 start working.
as you can see a bad ground with 1volt of noise would make 02 useless,
this is why 1 wire 02 were banned later.
and 3 and 4 wire have a heater and 2 good real grounds.
1 wire is a pain ,2wire ok up.
other tricks is exh man bolts or nuts put lock waster (star) under nut to make it bite into the rust. making head studs ,connect past the iron rust.( this seems the most easy)
