Q: Car sometimes stalls at red light

My car sometimes stalls when I'm stopped at a light.

Intermittent issues are among the most complex to diagnose because of the infrequency and all the variables that come into play. I have seen everything from low fuel pressure to a bad transmission torque converter cause a stalling situation when coming to a stop. Because of all the variables involved, my suggestion is to seek a mechanic for help, such as one from YourMechanic. The mechanic might try to see if what is called "freeze frame data" is stored in your cars computer. This is sort of a short film your cars computer takes when issues are happening. Information like this will aid in diagnosing an intermittent stalling problem such as this, but requires specialized tools to extract and experience to interpret the readings, so this is not something I suggest undertaking without professional help.
