Can a bad mass air flow sensor cause an engine to misfire ...

+

Answer (1 of 8): I could be, but I wouldn’t suspect it. It could be that the MAF registers way too little air mass, causing the engine to inject little fuel, resulting in a overly lean mixture. This lean mixture could misfire. Alternatively, it could register way to much air mass, causing too muc...
