Consequently, gasoline volatility cannot be currently estimated if the engine is cranked when the coolant temperature higher than 10°C but lower than the operative temperature; consequently, if the gasoline volatility is significantly different from expectations (i.e. from the gasoline volatility determined in the recent past), the fuel enrichment based on the estimated gasoline volatility is wrong and thus in the case of insufficient enrichment (excessively lean mixture) the idling engine presents a very irregular revolution speed and go out when pulling away.
