If two identical air temp sensors vary 3 degrees would I need to change the offset to make the ECU supply the engine with identical A/F and spark of the previous run?

Now that I’ve thought about it a faulty O2 could cause all kind of headaches.
Larry don't forget the 2 coil drivers, our's went bad after 3 years and we replaced every sensor before replacing the coil drivers which fixed the hot misfire and no start problem. Main harness also developed an open which would shut the engine off at the hit.
