Reasons for the slow growth of modern famous cars

Hello, there are many reasons for the slow speed increase. First, check whether there is a fault code. If there is, call up the fault code and analyze the cause of the fault. If not, check the air inlet pipe for leakage. Check whether the ignition time is appropriate. Then check the fuel injection system, such as fuel pressure and the working condition of the injector. Then check whether the ignition system, especially the key vibration sensor and igniter are working properly. Also check whether the throttle position sensor is normal, and check the working conditions of circuits and components related to fuel injection. Finally, check the cylinder pressure, valve clearance, spark plug operation and valve timing. In addition, some parts will also have an impact, such as: the three-way catalyst is blocked, too much carbon is deposited in the throttle, or there is something wrong with the circuit, the oil pump is faulty, and the gasoline grille is too dirty.
