Would an O2 sensor make your car stall?

Find out why the light is on. Maybe you broke or dislodged a connector when you replaced the sensor.

you check the gas filter when you have a bad one its run to a point the gas cant go throgh its stalls pump stop gas go back and start over again pressure push the dirt again let me no pierre

Its not the O2 sensors, or the coolant sensor or the thermostat. Get the codes read front the computer. Post those codes here before you spend any more money or install the other parts.

rewplace the O2 sensor have auotzone run dianostic test it is free.

your code must be P0131, a P0131 code refers to the first oxygen sensor on Bank 1. P0131 means the O2 oxygen sensor's voltage remained low for longer than 2 minutes. This is interpreted by the ECM as a low voltage condition and sets the MIL. Bank 1 Sensor 1 is located in front of the catalytic converter.
The solution is you can:
1.Replace faulty sensor.
2.Repair short, open, or high resistance on o2 signal circuit. FB.init("dd7d9e9681341cde77587bc6a2029f6f"); OBD-Codes.com on Facebook

throttle position sensor , or mass air flow sensor.

Depending on the engine in your explorer you may have 2,3 or 4 o2 sensors. these sensors are located screwed into the exhaust system, one before and one after the cat converter, if the truck has two converters then there will be 4 sensors. the problem you listed is that it stalls at idle or stop lights, this sounds alot like a bad idle air control valve which is very common on fords,also try cleaning the throtlebody, use cleaner and a tooth bruch open the throtle plate and clean good, if this doesnt help then i would look at the idle control valve. hope this helps.

okay, the o2 code can cause problems, theres a problem with one of the o2 sensors, theres 2 or 4 sensors,the repair was not done right or theres another bad o2 sensor, next thing i would check is the idle air control motor,this sounds like it sticks at time or just stops working,start with these things first,

When O2 sensor is bad the check engine light coming on is a warning. If you leave it go the computer will go into "limp" mode till it is replaced. You have to give the computer time to recalibrate itself after replacing, up to 150 or so....

The code says there is a problem, it does not say where in the circuit the problem is, it could be the wiring to the sensors, it could be the PCM (powertrain control module) in your case it sounds like an intake manifold vacuum leak.
