What happened to the acceleration of HNA Mazda 323 in 2005?

Hello, dear! If the throttle is not cleaned at 20000-30000, it is generally caused by low idle speed. If the throttle is dirty, the idle speed will be low and the air intake of the air conditioner will be insufficient. This may happen when accelerating. If it is caused by poor ignition or insufficient oil supply, it needs to be checked. It is not difficult to check frequently. Generally, it is caused by the failure of burner, ignition coil and oil pump.
