Which outcome occurs when gasoline direct injection (GDI) injectors experience sustained low fuel flow rates?

💡 Explanation

When GDI injectors have low flow, lean combustion occurs because the fuel-air mixture is deficient in fuel, increasing temperatures and thus, exhaust valve temperature. Therefore elevated valve temperatures results, not knocking, turbocharger issues, or oil dilution, which stem from rich mixtures or other mechanical failures.
