Never got back so don't know if problem was fixed.
Btw O2 sensor can cause the problems described and stalling can occur depending on the situation.
You would have to get the trouble codes fixed before continuing with further diagnostics.
Get the MAF, IAC and throttle body cleaned. They can cause erratic idling, stalling and hesitation.
