The symptoms of a faulty MAP sensor include significantly decreased fuel mileage, and roughness/jerking during acceleration. The air-to-fuel mixtures could be both lean and rich, and the idle could be off.
While a faulty MAF sensor can have the same roughness/jerkiness during acceleration a bad MAP sensor does, one of the more common symptoms is the engine dying immediately after start up. Any issue in the intake line causing the engine to receive unmetered air can also produce these symptoms (such as a torn intake hose between the MAF housing and throttle body).
If you think a faulty MAF or MAP sensor is the culprit, try cleaning it before replacing. See our article on how to clean MAF/MAP sensors.
