In case of idling during idling or a car that is thin under load / often running under idling or lean / rough idling or stalling, the MAF sensor needs to be replaced. MAF, also call top-quality air flow sensor, is a sensor used to determine the mass flow of air entering a fuel-injected internal combustion engine. Before installing the MAF, sure clean the air box and replace the air filter, otherwise "Code and Check Engine Light" may always be displayed even if the MAF is replaced with a new one..
