O2 sensors replaced: It's a puppy again!

[David Head]

Damn - and I'm a scientific kinda guy too. Guess pure logic and fact will have
to do. I have two Bosch O2 sensors in front of me - one is an original 74K mile
item that I clipped off my 1990 V8. The other 'fits' an 89 Taurus V6 3.0. Gee,
they both have the EXACT same Bosch 10 digit number STAMPED into the body of the
sensor. Now I'm certain those sneaky Germans would be making completely
different sensors and stamping the same internal pn on it just to confuse us car
guys.
