Group,

Probably been hashed around a few times but...

I have an '85 vanagon with a hot start problem:

--Starts fine cold (truth be told there is a slight hesitatation before it
starts cranking. But starts reliably. Has a new battery)

--After short drive, 15 minutes in cool weather, will not start. Will crank
and crank and crank, but will not start.

--Let cool, 15 minutes, fires right up.

Should I replace the (Bus Boys order numbers and descriptions):

035-906-265 UN Universal Oxygen Sensor, Bosch $25.55

Thanks for the advice,

Colin
