02 sensor
 

I have a '96 2500 with a 5.7, my problem is, o2 sensor, bank 2 sensor 1. I have to replace it about every 2 or 3 months. Any ideas ? Thanks, Gary

what brand of 02 sensor are you buying, and it is the same brand every time? if it is I would try another brand. if that does not take care of it I would say you have another problem that is not the 02 sensor.

Think I found the problem, found a broke ground wire behind the engine. Thanks for the help.
