I looked online for oxygen sensors for my 1997 Volkswagen Jetta. All resources that i researched says that there is both an upstream and a downstream o2 sensor. Well i ordered them and when i went to change them i could only find one, on the front side, or the intake of the catalytic converter. Another problem is that the plug connector is rectangular on the car and the plug on the o2 sensors that I bought are oval, and do not fit at all. I tried to look everywhere online to find an answer, but with no results at all. I Need help.
