I would expect a '92 to output three digit codes, though I'm really not sure on foreign models. Are you certain those aren't 173 and 158? A 158 would indicate a fault in the MAF circuit.
Beyond that, it's important to remember that codes point to circuits, not sensors. Be sure to inpsect the wiring between the offending sensor and the computer before blaming the sensor itself.

mmmmmmm i think that my X use only two digits, I repeat many times the test procedure and the result is the same all the time: codes 58 and 73 (only two digit)
Now, 73 is history, but 58 is still there
I´ll try two check the wires and conectors again, yesterday in the night I try, but everything is fine to mee
