2015 hyundai sonata car stalls while driving
my car stalls while driving. This last time it did
stall and won't stay running. It starts but won't
stay running when you let off the peddle.
I'd first clean your throttle body. If that doesn't work then you'll have to replace the throttle body.
Sounds like it could be related to the fuel injector.
Things should be tested before you replace them , guess work is not part of auto tech. Test alternator after you start it , . I'd say replace the IAC valve .
