does an o2 sensor go bad if it is left on the manifold that is not in use.

 

it can if it's left outside where moisture can get to it

 

Typically no. If moisture condenses on/within it... like rain, and then freezes, the ceramic thimble can shatter.

 

I have been reading your old posts about O2 sensors and wondered what happened to the unit you and your partner were working on?

I have just assembled a rev 5 DIY_WB board before I had a sensor but just found one tonight. You presented a wealth of knowledge and I enjoyed reading it all.

Since finding the threads about AFR I have learned alot that I wish I knew back when I was Dragracing seriously, course this stuff was just a dream then.
I am doing this to help tune my Son's 68 Camaro,we've had it since '85.

I have also read a ton about reading plugs and found out everything I didn't know back when no one would tell you how to do it in the old days. An AFR would sure go a long way to fill in the gaps.


Do you know what signal a person would be able to use for data logging RPM? I think between RPM and AFR you could really dial in a carb now that I have learned there are about 6 or 7 different things to tune on a Holley carb.


Boy were we dumb in the old days.


Thanks for any help, it's all very interesting,
Terry
