Q: How are you, my new Corolla is bought. However, due to long-term home of Lianche (only Idle to drive, do not Caiyou Men), the car is idling when Meijin, and at the starting The idling will shake if the car sit idle 4-5 individuals is not fixed, will buffeting, 4 S stores to open to the inspection is carbon deposition, to clean up the throttle, the car less buffeting, but still You Jin did not the original, sometimes idling will still buffeting, now my car before travelling 2,500 km, the chef said to me when 3,000 km to the first-if the car idling buffeting it will help me do the cleaning for demolition (carbon deposition ), But the car was done on a 2,500 km-free demolition cleansing carbon deposition on the engine, Circuit equipment, such as harm?
What I do first-time
I have the oil is used instead of the 15 W/40?
Guangdong can be used 10 w/30?
Answer: Dear users, Hello: carbon deposition in addition to most of the fuel quality reasons, there is the long-term use of the accumulated results, in fact, caused by improper use of carbon deposition users also can not be ignored.
As you say whether the buffeting from the engine caused by carbon deposition to further inspection, demolition-free cleaning carbon deposition on the engine, Circuit and so will not cause harm.
With 10 w/30 than 15 W/40 good, the proposed use of all oil, the engine had better protection.
Please do not forget 5000 KM for first-oh.
If you have any questions about using the car, go online to the experts for experts to answer Links cold start when five vehicles often jitter look at the possible reasons for the low energy ignition when the vehicle cold-start the engine if the temperature is low, fuel and lubricants The lower the temperature, more fuel injection to meet the dynamic demands.
After prolonged use, the spark plug the gap easily change the pole, leading to decreased energy ignition, fuel atomization bad, so that vehicles in jitter.
In addition, the ignition coil aging, aging power lines or the spark plug leakage, the same can lead to reduced ignition energy.
Mixing ratio inappropriate in a closed-loop control of the vehicle, the oxygen sensor the minimum temperature is 370 degrees Celsius, if the vehicle has just started, the temperature in the exhaust pipe of less than 370 degrees Celsius, oxygen sensor will not work.
At this time ECU (lane computer) lapse of judgement, their bodies through the implementation of the oil and gas mixture, ignition time for the control of errors, thereby reducing the vehicle's power output, a jitter phenomenon.
Carbon Deposit if the inlet valve and the engine inlet valve and a carbon deposition, which can absorb carbon deposition amount of fuel, ECU errors in judgement, the same can not need the power, jitter on the phenomenon of the inevitable.
The cylinder in different conditions after prolonged use, the cylinder spark plug ignition control space and time differences arise, but no such deviation of ECU, still on the "them" equal treatment, which has practical and theoretical errors The results have some power too small cylinder

The water temperature sensor temperature sensor is malfunctioning computer judge the status of the engine was an important basis for one.
The water temperature sensor failure will lead to computer-controlled injection of deviation, causing a vibration.
Fuel cleaning agent - and the removal of carbon deposition glial glial a magic weapon with the formation of carbon deposition in the fuel storage, transport, prone to oxidation, the jelly-generated material.
These jelly-like material on the solubility of gasoline can be divided into: soluble resin and non-Sol quality.
Sol also known as quality can not be sediment, and its accession to the vehicle's fuel tank with fuel, we will adhere to the fuel filter, plug the filter media, to reduce the volume of oil so that the volume of oil shortage, fuel atomization bad, Which combustible gas mixture thinning

Soluble resin into the combustion chamber and gasoline together, the intake valve will be in Detroit at the top, piston ring slot, the combustion chamber, spark plugs and other parts of the formation of many hard carbon deposition, the valve closed, to strictly decrease engine performance, such as Going to accelerate, idling instability and stall, jitter, detonation and a series of fault
