I believe that many car owners will encounter the small car problem of stepping on the accelerator deeply to accelerate the engine and yelling. Then I will introduce you to the solution to this problem, hoping to help you solve the problem. The possible reasons for the boring speed increase of cars are:

1. There is something wrong with the ignition system, such as the aging of the ignition coil and the failure to replace the spark plug for a long time, resulting in insufficient ignition energy, poor combustion, weak engine acceleration and engine fault light;

Second, the fuel system failure system failure leads to low pressure. Insufficient fuel injection will lead to weak engine acceleration;

3. Too much carbon deposition in the engine leads to poor fuel atomization, poor combustion of fire and gas, too much exhaust gas and weak engine acceleration;

4. Engine system failure causes the engine to enter an emergency operation state, which further limits the power output of the engine and leads to weak acceleration. Such as engine sensor failure, such as oxygen sensor, air flow sensor, crankshaft position sensor, knock sensor, etc. The failure of these sensor signals will cause the engine to enter an emergency operation state, which will make the engine unable to accelerate;

5. Three-way catalysis or turbocharger is damaged. In this case, we have to go to the maintenance organization to diagnose the relevant fault codes with a computer and troubleshoot the fault according to the fault codes.
