I trekked down to Pep Boys today and got a Bosch oxygen sensor for my 1994 SL2 (the one that goes in the exhaust manifold).
But it appears to be the wrong one...
The part number I got is Bosch 13043, single wire unheated. The part I removed from my car has a single wire as well, but the connector is slightly different, so the one I bought won't fit.
Not trusting retailers website, I went to bosch.com and after some searching, it lists the Bosch 13050 for my car, which has a description of "four wire, heated, use in California" (which is where I live...)
What gives? I'm tempted to return the Bosch part to Pep Boys and head to the Saturn dealer and get the OEM part (at 3X the price... ugh...)
