At a stoplight my car shuts off then i have to crank the car up and the rpm is around 1200 on idle. My Epc light comes on. What could be the issue? I changed my spark plugs coilpacks and maf, pstream o2 sensor and are all brand new and OEM AUDI.

 

Hello, sometimes its the mass airflow sensor, you can try cleaning it off first, it's a delicate sensor so be careful.
Get the codes first though!

 

What codes are being thrown?
