Others beside myself have looked at my O2 scans and it is working perfectly. Like Smellbird said, I don't want to risk screwing up my mileage. Who knows, maybe it would go up a little more with a new one. But, I'll leave well enough alone.

This is what the one in my 95 is doing.... It has slowed down a handfull lately... I was doing 20-21 in town with my foot on it... Mine is also hanging on rich longer as opposed to the quick cycling...

Now see if you can break 30mpg
