Hey All,

I've been having this problem for a couple of months now. When the cars cold it accelerates fine with no hesitation. But once warm the car bogs from 1K and then from 2-3K, it's like a loss of power. This is actually noticable in my recent dyno. I've replaced everything apart from the o2 sensor and the distributor ignitor / coil. So is this a sign of a bad o2 sensor?

To diagnose a faulty o2 sensor you need to look at the lambda and fuel trims. The symptoms you describe sound more like general tuning, but looking at the lambda would be a good start with loss of power issues too.
