2016 Hyundai ELANTRA stalling

Hello, the oil light flashing is likely the result of an engine idle speed that is too low resulting in an engine stall. However, to be safe, it'd be a good idea to measure base engine oil pressure, as oil pressure that is too low can cause all kinds of problems. Although a "local parts store" "scan" is not really a diagnostic test, it does seem that having no diagnostic trouble codes rules out a few areas, such has air - fuel mixture concerns, ignition concerns. I'd probably have a fuel pressure test performed to see if a low fuel pressure concern is present -- typically low fuel pressure does not set any codes. Other than that, comprehensive hands on diagnostic testing is needed to figure out what is going on. You'll need to consult a local shop near you with some well trained technicians and good technical resources.
