Which risk increases when intake valve deposits disrupt fuel vaporization in a GDI engine?

💡 Explanation

Lean misfire risk increases because intake valve deposits absorb fuel, inhibiting the proper air-fuel mixture. This is due to fuel film absorption. Therefore, a lean mixture is created, rather than a homogenous charge leading to efficient combustion, especially at cold start.
