Methods and systems are provided for reducing or avoiding engine hesitation and/or stall during engine idle conditions. In one example, a method may include inferring an engine idle condition, and in response, controlling a speed of an engine to a compensated engine idle speed that is a function of an extent to which a canister purge valve that regulates an amount of fluid flow to the engine from a fuel system and/or an evaporative emissions system, is degraded. In this way, an amount of fuel utilized to compensate for the degraded canister purge valve may be proportionate to the extent to which the canister purge valve is degraded.
