this probly won['t help your question at all. but i ran across this in summit the other day and i'm pretty sure i'm going to buy it. there won't be any guessing whether i'm rich or lean i'll know for sure from idle all the way up where i'm at.
http://store.summitracing.com/partde...art=EDL%2D6593 i think i'm gonna make a face for it to mount it in the ash tray, and when the tray is flipped up you won't be able to see it

1 should work....most EFI vehicles are set up like that...
I would love to get one of those myself....but don't the O2 sensors only work well around 14.7:1 air/fuel ratio? I think the accuarcy on some gets really poor as they get farther and farther away from 14.7. 14.7 is great for cruising under light throttle....but more like 12:1 is better for power  Oh yeah....i saw a cheap air/fuel guage for $24 at Autozone the other day.......don't think it came with an 02 sensor though....but it is 1/5 the cost of the Edelbrock sensor.

Funny, I thought my 94 Caprice had two.....95's up have four from what I hear.
Wouldn't you want one on each header?
