Re: Engine shuts off at a slow to stop
The error codes are heated oxygen sensor at it's limits and too lean on mixture bank 1. The oxygen sensor could be the cause of this lean mixture. I would replace the oxygen sensor. There are 2 sensors, one before the catalytic converter and one after the catalytic converter. The one you want to replace is on the engine side of the catalytic converter.
In addition to the above IAC (Idle Air Control)could be dirty and may need to be cleaned. It is loacated on top of the throttle body. It looks like a small motor the size of a C cell battery. It has a wire clip onto it and is attatched to the throttle body with 2 head size 8 mm bolts. Take it off and spray it with WD 40 on both sides of the flange cavities. I doubt that you need a new one because if that were true it would be malfunctioning all the time, not just once in a while. I would do the above before replacing the intake gasket. Coolant flows through the intake gasket and it would be leaking if it was bad. The water from your A/C is condensation and that is normal to the operation of the A/C. There is nothing wrong with your air.
