What are the symptoms of bad spark plugs?

Symptoms of bad spark plugs: 1. Difficulty starting and stalling for no reason. A clear symptom is difficulty in starting the car. Bad spark plugs can lead to insufficient ignition energy, or even failure to generate high voltage electricity, preventing the creation of sparks to ignite the fuel-air mixture in the cylinder, making it naturally impossible to start the car. Even if the car can start, it may suddenly stall. 2. Lack of power and excessive exhaust emissions. Bad spark plugs cause incomplete combustion of the fuel-air mixture in the engine, resulting in insufficient power. The replacement interval for spark plugs generally ranges from 20,000 to 100,000 kilometers, varying with different materials. Ordinary nickel alloy spark plugs should be replaced approximately every 30,000 kilometers, while better iridium or platinum spark plugs can last 60,000 to 80,000 kilometers before replacement. For 4-cylinder models, if one spark plug is damaged, it is recommended to replace all four together, as replacing only one may affect overall performance.

At the same time, the longer the idling time when parked, the greater the fuel consumption, so try to minimize idling time. Additionally, avoid sudden acceleration, hard stepping on the accelerator, and driving at low RPMs. Factors affecting fuel consumption: Various driving conditions such as acceleration, deceleration, braking, and engine idling, as well as load capacity, temperature, and whether the air conditioning is on, can all affect the vehicle's fuel consumption.

What to Do About Jerking After CNG Conversion?

Issues with the gas injection rail can prevent the air-fuel mixture from reaching the normal concentration level, naturally causing the vehicle to jerk. It is highly likely that insufficient ignition energy is causing the jerking. For example, if the spark plugs have reached the end of their lifespan, they need to be replaced. Another possibility is damage to the mainboard of the vehicle's computer. Since the actual vehicle cannot be inspected, an accurate diagnosis cannot be made.

What to Do If the Windshield Washer Reservoir Is Leaking?

If it is not fastened properly, the reservoir cap should be securely fastened, and then check whether the car's water tank leakage has improved. The water inside the tank will seep out under pressure, thus identifying the location of the car's water tank leakage, after which a repair method can be determined. Check whether there are any signs of emulsification in the engine oil. If emulsification is found, the engine should be disassembled immediately to replace the cylinder gasket.
