After changing the spark plug, the throttle is very meaty. After changing the spark plug, increase the speed.

After changing the spark plug, there was a speed increase, and there was no good experience when using the throttle.If this happens during driving after changing the spark plug, it is possible that the gearbox may malfunction and the inside of the gearboxYuanParts failure or improper maintenance can cause freezing when speeding up. It may also be a failure of the automobile oil circuit, such as insufficient fuel injection pressure, electronic fuel injection failure, etc.

At the same time, it is not ruled out that the spark plug itself is a problem. Although it is just replaced, there may be damage to the spark plug itself. Poor ignition of the spark plug may also easily cause the driving experience of a meal during driving.
If the spark plug has just been replaced, and there is a bad phenomenon while driving, go to the 4S shop for inspection and maintenance in time to solve the existing safety hazards in time.

The following are some manifestations of spark plug failure

1. The car's ignition is poor, or even unable to start, and often requires multiple ignitions;

2. Insufficient power, it is obvious that the car is weak during driving;

3. Fuel consumption increases. Compared with usual, cars consume more fuel;

4. The engine shakes, and the shake of the vehicle can be felt during driving;

5. The flameout phenomenon occurs, and flameout is easy to occur during driving;

6. Exhaust gas emission is not up to standard, fuel combustion is insufficient due to spark plug failure, and the gas content produced does not meet the requirements.
