I'm going to let some electronics crackerjack answer that question, but my
understanding is thqt the coolant temp sensor 2 will override, or work with
the O2 sensor and enrich the fuel mix to keep the van from stalling until it
reaches normal operating temperature.
Help me, Mr. Crackerjack!

Wouldn't my crackerjack O2 monitor show that? It does the normal
middle-of-the-range flatline display while the ECU is waiting for the O2
sensor to warm up, then your usual fairly rapid back and forth sawtooth
thing while driving.
