Need to replace O2 sensor, where is it?
 
Ive got around 100k now on the old Boxster and I have a CEL. Code is P0134:
O2 sensor ahead of cat. conv. Cylinder (1-3).

I know there are 4 sensors, but I don't know which cylinders are (1-3), is this the passenger side or drivers side?

Here's another link as to the location. One of the easiest things you'll do.

........
That code is for an interruption of signal from the O2 sensor to the DME, so check the wiring harness (signal and ground) also.
