If There Are 4 Signs in The Car, The Spark Plug Needs to Be Replaced

There are many parts on the car, and they should be replaced in time after long-term use, otherwise there will be many problems during use. Spark plugs are a part that needs to be replaced frequently during car maintenance because it is easy to damage. Spark plugs need to be replaced frequently. When should spark plugs be replaced?

First, the car is difficult to start. The car cannot start normally without spark plugs. If the spark plug fails, the car will be difficult to start. Since the spark plug cannot provide enough energy for ignition, the engine cannot start normally. In addition, if there is obvious frustration when the car starts, the spark plug should also be checked, because it may be caused by excessive wear of the spark plug.

Second, the car often shakes during driving. The car shakes while driving. If it is not a three-cylinder engine, then there is a problem with the car engine. This situation is basically caused by serious carbon deposits in the car engine. If there is a large amount of carbon deposited on the spark plug, the power of the car will be strong and weak, and the final feedback is engine shaking.

Third, the car cannot climb. This situation is actually the later manifestation of the second symptom, because too much carbon deposits on the spark plugs lead to insufficient fuel combustion, which will make the engine carbon deposits more serious and reduce the engine's power performance. This is equivalent to adding a lot of pressure to the engine. Therefore, when climbing a hill, more powerful power is needed, and the engine is relatively weak.

Finally, the car's fuel consumption increases and smoke comes out of the exhaust pipe. If the spark plug is abnormal, the fuel consumption will increase significantly, which is caused by insufficient fuel combustion. Since the gasoline is not completely burned, the exhaust gas produced after the gasoline is burned is also different, such as black smoke. If this happens, please replace the spark plug as soon as possible, otherwise it will affect the three-way catalyst.
