The result is poor engine performance because the intake valve cant let air into the chamber to create combustion, and the exhaust valve cant release the toxic gas from the engine as efficiently. The job of the catalyst converter is to cut down the amount of pollution generated from the exhaust gasses. What exactly could be the problem? In that case, the engines functionality will be negatively impacted and will likely not function properly. 10,000 MILES. The responsibility of the fuel pump is to take fuel from the gas tank and transfer it into the engine of the vehicle. Do you know where its coming from? The spark plugs transmit the electrical signal sent by the ignition coil to the internal combustion chamber to ignite the fuel and air mixture by an electric spark.

As you might expect, an acceleration issue could occur because of a problem with the cars engine. A clogged air filter starves an engine of much-needed air, skewing the air/fuel mixture that affects acceleration. The camshaft position sensor is responsible for sending camshaft speed data to the ECM, which it then uses to optimize fuel injection and ignition timing. The oxygen sensor is positioned inside of the exhaust stream. You can fix this issue by following a few simple steps. The function of the fuel filter is to remove any impurities in the gasoline. It does not come as a surprise that your car needs fuel to keep going and accelerating. If the MAF readings match with the oxygen sensor readings, then this means your car is in perfect running condition. An oxygen sensor in this system measures the gases leaving the car and sends this data to the ECM. Hiccups in air and fuel delivery and sensor issues are the main causes of poor acceleration.
