Which outcome is most likely upon the failure of a gasoline direct injector’s (GDI) anti-soakback mechanism?

💡 Explanation

Fuel leaks into is likely because the anti-soakback mechanism prevents fuel seepage after the engine is shut off, utilizing a check valve; therefore, raw fuel floods the intake port, rather than other thermal or mechanical effects resulting from incorrect combustion.
