[s-cars] Oxygen sensor musings...

And what are you getting now?

I did the same thing, but I bought a bosch that was for another make and 
spliced it on. My gas mileage actually got worse. Instead of getting the 
20.8 I was unsatisfied with, I went down to 19.8....

Now I'm back up to 20.8ish, but I'd hoped to get some improvement from this. 
I'm not sure what I should be aiming for here, but I suspect that my heavy 
right foot has something to do with it.
