Car keeps stalling

Spark plugs & wires changed lately?

I just did a tune up a few months ago

Could it be bad gas

Well there is a lot of things it could be and check. If check engine light is on have it scanned at a auto parts store. Make sure all electrical connectors are tight. Clean MAF sensor in air intake with MAF cleaner do not touch it just spray with approved MAF cleaner, Take off throttle body and IACV and clean them very good everywhere in side but gently with throttle body cleaner the throttle body has throttle position sensor in it and the IACV is a sensor, will need to reinstall with new gaskets. We need to rule them out, they can be tested with multimeter too, its best to clean them first as if they fail it can mean they need to be cleaned and are in good condition. I'd start there and of course check fuses. I doubt bad gas.

Do you drive it everyday or has it been sitting a long time? Check or replace air filter.

I drive it every day. Its been doing it for about a week now

My check engine light isn't on either

Other than checking/cleaning the above Confirm fuel pressure and fuel filter, air filter, Test the Ignition control module and coils, PCM.
