[tech]: anybody? o2 sensor question...

[abatzis2@hotmail.com (Michael Abatzis)]

thanks; i was trying to cut out the middle man. bentley's test for the o2 
sensor is "see if the dpr current is fluctuating". if it is, great, the 
sensor's working, but if not it could be any number of things. i suspected 
the sensor, and wanted to test it directly.
