In cold weather, the car will obviously stop shaking.

First, the temperature is low. When the temperature is low, the exhaust pipe temperature will also decrease, and the oxygen sensor is also the lowest working temperature, so the ECU of the vehicle can't get accurate data, which makes the ignition and oil-gas mixture control error, which leads to the weakening and jitter of the vehicle power output. If this happens, don't worry at all. Wait for 30 to 40 seconds after the cold start of the car. When the temperature of the car rises, the jitter will disappear.

Second, car carbon deposition. Throttle carbon deposit is sticky, assuming that the original injection of 100 engine oil, because the carbon deposit adsorption is only 90%, it can not reach the amount of gasoline required for combustion, which will naturally produce jitter. If the jitter is caused by carbon deposition, it is generally enough to clean the throttle and nozzle. This is only possible if the new car runs normally for 30,000 to 40,000 kilometers.

Third, the spark plug is aging. When the spark gap is different after spark plug aging, the power of each cylinder will be deviated, which will affect the power and lead to jitter. At present, the spark plugs of family cars are generally made of nickel alloy, which can only be replaced after 20 thousand to 30 thousand kilometers of normal driving. If it is a platinum spark plug, it can drive 40 thousand to 50 thousand kilometers.
