Check engine light on - think it is bad O2 sensor - is there any
damage that can result of running the van with out replacing this

be running well with no change in mileage, etc. Do not want to fork
over the $200 to $350 to replace it right not. Do any of the auto
parts stores read the car computer for a error code free?

Most parts stores will read the the codes for free. Alternately, Harbor
Freight sells the readers, and they will work with most vehicles with OBD.

Here's one for twenty bucks:

If you need to replace the sensor, do it yourself, it ain't rocket surgery.
