What would cause my 2014 Kiaforte to stall when slowingdown or coming to a stop?

It sounds like the engine speed of the vehicle is becoming too low as you slow. This is due to either a fuel control issue or an air intake issue. You could have a vacuum leak. You could have an air intake restriction, or even an exhaust restriction. Troubleshooting will yield the cause of your concern.

I know this is 2 years old, but wanted to know if you found out what it was causing it? All 3 mechanics I went to couldn't find the problem! If anyone has the same issue, please let me know what it was that solved it! Thanks!
