When I stepped on the accelerator, I found that the acceleration was not obvious, there was a lack of power, and the engine made a hysterical noise. The times most likely to occur are when the engine is hot or cold, or when it is low on oil. The causes of these problems can be divided into air filter, spark plug, ignition wire, gasoline, fuel filter, carburetor, oil pump and other problems. Check if the air filter is dirty, if the spark plug is old and needs to be replaced, if the ignition coil is broken, and if the gasoline is not clean, such as water in the fuel line. 'oil. Also check the oil pump.
When driving, acceleration is normal and ignition may be normal. However, if you drive at a constant speed, you find that the engine speed is too high but the speed still seems unable to operate. increase. Try to checkr the coolant. Oil pressure is too high or too low. Check the pressure gauge. There may be a problem with the ignition time setting, which may also cause such symptoms. As with others, it could be a problem internal to the engine, such as a clogged EGR valve.
The motor makes a whistling sound, which sounds like steam or air coming out of the motor. Typically, after hearing this noise, the engine will quickly lose power. Possible problem, engine overheats, check cooling system. The exhaust system is clogged, the suction pipe is leaking or broken.
When accelerating, the engine will make a whirring sound, or it will also sound when decelerating. In short, the sound will change as the regime changes. The possible reason is lack of power steering oil, fill it up. The generator bearings could be damaged. Problems with thePower steering pump and water pump will produce similar noises.
A loud noise comes from the exhaust. Sometimes a similar noise comes from the front part. The main problem is the exhaust system. Check if the exhaust pipe is broken.
When the motor is running, it makes a clicking sound, as if something is hitting metal. When accelerating or driving, you may not hear anything. This may be caused by the cylinder valve, which can be changed by adjusting the valve. Lack of engine oil can also cause similar problems. Additionally, engine oil pressure is relatively low.
When you press the accelerator pedal, you will hear a clicking noise coming from the exhaust pipe. The sound may not be very loud, the car will not run abnormally, and fuel consumption will increase. . It is recommended to check that the muffler and tuyau exhaust are not damaged.
The motor makes a kicking sound, like the sound of a pencil hitting the table. The sound increases as engine speed increases. The possible cause is that there is dirt inside the engine. It is recommended to change the oil, filter and clean the engine. Others may be a valve problem.
There may be no problem while driving, but there will be a clicking noise when accelerating. It is recommended to check the ignition time setting. The engine may be overheating, the engine may have carbon deposits or carbon deposits. the quality of the oil may be poor. Higher oil quality is required.
High-pitched, squeal-like noises, especially when the air conditioner is on, the weather is cooler, and it is more obvious when slowing down. Possible reasons are that the drive belt is slipping and thedriving direction is too high, reaching the limit. The belt is too loose, tightening the belt may solve the problem.
When you drive at low speed or when you accelerate the gas pedal, something will come out from under the engine. There are sounds like crown, crown, etc., especially when the weather is more costs. It is recommended to raise the frame and check if there is a heat shield between the exhaust pipe and the ground. This may be due to the aging of the heat shield. It can be fixed by replacing it or removing it.
