Had a 02 go bad on the mach and replaced it with a brand new Bosch part. Less than 1000 miles later and the CEL comes on again for the drivers side 02, which I just replaced. To make sure it was the sensor not something else, I swapped it with the passenger one and cleared the code with the tuner. the code for other side comes on, and wont go away except for about 30 minutes yesterday (wtf).
Is it normal for one of these to fail so soon? These things are kinda expensive to be replacing every 1000 miles or less.
