Abstract
Methods and systems are provided for accurately determining cylinder fueling errors during an automatic engine restart. Fueling errors may be learned during a preceding engine restart on a cylinder-specific and combustion event-specific basis. The learned fueling errors may then be applied during a subsequent engine restart on the same cylinder-specific and combustion event-specific basis to better anticipate and compensate for engine cranking air-to-fuel ratio deviations.
