Hello everyone,

I am replacing the pre-catalytic oxygen sensor in a 93 300TE. I have no trouble locating the spark plug like socket in the exhaust pipe. However, the other end of the sensor cable goes into a hole in the car and goes ... where? A description of the replacement process would be very much appreciated.

Also, I have to replace the mass air flow meter. Don't have the part yet. I understand there are two types, new and old. A description of the replacement process for this part would also be nice.

Regards,
Simulaman
