I put a used motor in one for a customer a while back. The salvage yard snipped the wires to some sensors, and one 02 sensor, so I just grabbed a new one from the parts store and installed the engine .
Took me another whole day to make it run right, with the same symptoms you had . I wired the old 02 sensor back together, stuck it in,and it ran perfect again .
Weird. There are a few cars that do not like aftermarket 02 sensors. Toyota being one of them also .

I tried four (!) different Chrysler/MB O2 sensors from various (non OEM) brands that were listed as compatible. They all worked for a while, then lit "voltage too high" CE...
I should have known better considering that original fault was O2 heater circuit and not O2 itself.
Anyway, bus rolls on...hauling 2 by 4:s, kids, bicycles and whatnot

I have to put block heater and coupe heater in it though, it takes lot of gas to defrost in the morning
