Since my van is not wanting to start unless I hold the gas pedal to the
floor and has also started trying to die when she idles down I am thinking
about replacing the O2 sensor tomorrow.  My FLAPS has a generic Bosch one
for ~$22 and a VW branded one for about 2 to 3 times more.  I don't
remember the exact price of the VW one.

My question is, is the generic Bosch one the same or should I go with the
VW branded one?

TIA,
