Hello, recently I've had soem trouble with my 2001 Acura MDX; the first problem was a malfunctioning battery (replaced it) but the second is that the car shuts off at low RPM occasionally. For example, I turned on my car and was sitting in the garage and it randomly shut off. Then when I was at a red light a couple of weeks later the engine turned off again. Now the car has no problem starting back up, but I want to know why it keeps shutting off on me? I did notive that it happened more times during the winter when it was very cold, but that may not be relevant. It's got 155,000 miles on it but runs completely fine, thoughts?

I don't remember if this model year came with throttle by wire or if there's still a cable attached to the throttle body. If it's still mechanical (cable throttle), I'd make sure that the throttle cable adjustment is set correctly, as well as idle speed. While you're there, you can also remove the inlet hose off and do a quick throttle body cleaning (get a few cans of carb cleaner and go to town on that bad boy). I've seen this more on the 4-cyl model Hondas, and sometimes it's the idle control valve that sticks or goes bad and when it does, it doesn't always throw a code.
