Check Engine Light is on. Pops O2 sensor but car is acting funny.
When I slow to a stop My car will stall out sometimes, but it will restart right away. The interior lights will start to flicker, and the head lights and radio will go on and off when I'm slowing down or at an idle. But the car will not stall out in park. I was told that maybe it would be the trans range sensor but I can't find any info about it, and it's not reading that when I had Auto Zone hook it up to their computer.

Re: Check Engine Light is on. Pops O2 sensor but car is...
This sounds like the loss of electrical power because of the lights.Any chance of a broken engine/transmission mount allowing to much movement and breaking a connection? Along this same line, look for a vacuum leak that occurs while in gear. If the o2 sensor code is for a lean condition a vacuum leak could case it and the drivability condition /stalling you are getting. Hope this helps and rate me please!!

I would not recommend throwing parts at it. If the computer or O2 sensor is the problem you should have a check engine light on the dash. Usually the EGR valve causes a problem when you are slowing down not just on turns. If you have not replaced the fuel filter this year I would do that to scratch it off the list. The throttle position sensor could be failing but not to the point of turning on the check engine light. It can be tested with a meter. You need to find out if you are loosing fuel pressure or creating a vac leak when the stall happens. Could be a vac hose or something that is moving when you are moving the engine.
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.

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,
is this a 4 or 6 cylinder? if a 4 cylinder it will only have 2 o2 sensors V6 will have 4 o2 senors which the sensor will be the right side of the engine first sensor. 1st sensor on exhaust, I recommend if you change one change all, as this will make the computer when it rechecks the system you have all clean/fast responding sensors.
if you have a slow response it means the sensor is dirty and not reading well, which is usually caused by minor misfires that the engine computer dismisses, so a tune up would be recommended too.
RPM's up and down check EGR valve and sensor. EGR valve and sensor control idle. That's why your getting the surging on rpm's and this could be giving out the other codes. If mass flow was bad car will not start and the same for the map sensor. O2 sensor measures gas and air for right mixer. TPS controls 0-60 speed as in throttle respons.
