I was considering throwing an O2 sensor at the problem, but wanted to get some data first. So, the O2 values look normal, but the cross counts mean it's spending too much time either lean or rich, right?
Does 'lazy' mean it's just taking too long to sense, and report, the changes?
If you were to replace it, would you choose a wide-band sensor? Or a stock one? And, if stock, a Bosch or an AC/Delco?
