WebJul 17, 2024 · The engine computer (PCM) calculates how much fuel to inject based on the mass air flow sensor measurements. If there is a vacuum leak anywhere between the engine and the mass air flow sensor, it causes "unmetered" air to enter the system. This causes the actual air flow to be higher than the mass air flow sensor measures. WebFeb 11, 2011 · Misfire is caused when a cylinder doesn't ignite its fuel mixture. Suspect a bad plug, coil, or wire. This will not be caused by a mass airflow sensor, that can cause a rough idle or bad fuel economy, but will not cause an individual cylinder to misfire. Driving with a continuous misfire condition will eventually destroy your catalytic converter.
