Weird O2 readings.....

Dave, my notes show AC AFS-16P as the stock sensor but my maintenance records show my last replacement was AFS-20. Do you happen to know what the difference is?
Thanks.

No I don't know the difference. Although I can say with certainty, that in the 25 years of owning/tuning my 86, I've never heard of the 16P. I know my original was a 2x something. Just can't remember whether it was a 20, 21 or 22.

I'm not sure where the # afs-16P came from, as my notes go back to 87. I rechecked my maintenance records and found that you're right the original was afs-20. I did try an afs-22 at one time because my friend's GNX came with one. Switched back after a month since there was no gain in horsepower (ha, ha).

Happy Holidays
