Hi Rusty;=20
        Considering that my O2 sensor exhibits similar behavior as = yours and I=20 also measure downstream EGT temps (after turbo) right beside the O2 = sensor and=20 only see temps in the 700F range, I can't help but think that maybe = the low=20 temps are possibly the cause of the problem.

        I=20 realize that you no longer have the turbo but you are measuring twice = as far=20 downstream as I. It doesn't seem likely the EGT could cool off enough = in this=20 distance, but why don't you clamp one of your spare T/C inputs to this = location and find out for us?
