Mazda 5 1500 rpm brake pedal accelerator pedal jitter.

Generally, it is transmitted to the accelerator pedal because of excessive engine jitter.

Mazda 5 1500 rpm brake pedal vibration is generally caused by excessive engine vibration, which will be transmitted to the accelerator pedal. The possible fault points are as follows: the lack of engine cylinders may cause one or more cylinders to fail, so the engine jitter is transmitted to the accelerator pedal. Common failure points of cylinder lack are: spark plug failure, ignition module failure, poor gasoline quality and so on. It may be that the engine throttle is too dirty, causing the engine to shake. It is recommended to check the throttle. If it is too dirty, it needs cleaning. It may be that the rubber parts inside the engine and gearbox bracket are aging, so this part can't absorb the vibration when the engine is working, so the vibration will be transmitted to the accelerator pedal. The above are common fault points, so it is recommended to check them as soon as possible.
