i need to know something about scanning your 02 sensors, when i scan mine i changed my front driver 02 because it was dipping down and totally cutting out making my car run really shitty so i went to autozone and replaced it, this one doesnt dip down as low and cut out but my issue is looking at the guages in hp tuners i see 3 of them side by side and the driver always doesnt follow exactly the same like the other sensors do?
