Sagittal bronchiectasis, accompanied by the sound of gas when stepping on the gas pedal.

The causes of bronchiectasis accompanied by gas sounds are as follows:

1 08 sagitar deflagration is a phenomenon that the incompletely combusted mixture burns in the exhaust pipe and makes noise. The causes of shooting are inaccurate or disordered ignition timing, weak or no fire caused by high-voltage coil failure, improper spark plug electrode gap, poor idle valve, unsealed main injector or cold start injector, too high oil circuit pressure, unsealed exhaust valve or too low cylinder pressure.

2. The surge caused by the periodic fluctuation of engine speed is due to the blockage of the vacuum interface of the intake pipe, which leads to the pressure sensor not being able to sense the vacuum degree of the intake pipe immediately, the aging of the timing belt, the exhaust failure of EGR system and the failure of turbocharger system.
