Car turned off while in drive idling with my foot on the brake. I think the rpm is too low, but I constantly leave the car in idle in park and never has stalled
What is your question?
The only engine code that has popped up is for the AMF sensor. I cleaned the AMF sensor and the engine code went away. Now I had a stall out while at a light, my car started back up and was fine, but I have noticed of late that the rpm seems really low at idle, can't find a tachometer to do a stall-speed test. I'm just hoping it's not a transmission problem: my car is a 2010 Mazda 3 w/ 180,000 miles.

It would be prudent to be checking fuel delivery and air intake coming into the engine. Even though your code went away, what do the actual fuel trims look like? What code was it? There is no code saying a sensor is faulty or dirty. Troubleshooting is needed to find out what is happening.
You could have a mass air leak, a vacuum leak, a fuel delivery issue. It's hard to know without test equipment hooked up analyzing data.
