oxygen sensor code

1999 ranger with a 160000 miles unknown history. Keeping getting a check engine light with code po133 o2 sensor ckt slow response bank 1 sensor 1.. I have gotten this code twice and had it cleared, hasn't come back for round three. So should i just assume the is thing proably hasn't been changed in a while, if ever? and just bite the bullet and change it? I am hoping that is all it is. Any preferences on brand? I know bosch spark plugs aren't really liked on here, how are their oxygen sensors?? Any preferences on brand?

later!! chris

If you aren't getting any other lean codes, then it's probably the 02 sensor. Bosch 02 sensors are fine for your Ranger.

Actually, Bosch sensors are OEM for some Fords.
