I have a 96 ford xlt 2wd explorer. It down some time back wouldnt pass emissions. Get it read and was saying bank 1 and bank 2 are running lean. Would that be the 2 sensors before or after the cat coverter.
That would be the front sensors but it is extremely unlikely that both O2 sensors went bad at the same time, it's far more likely something else is making the motor run lean. Any other codes?
