Nanyang owners Mr. Zhou asked: New Bora, ran more than ten thousand kilometers, just done twice maintenance. After the second maintenance is done, the engine exhaust fault warning light is lit, but each time the alarm light will disappear in less than three days will be bright. And then hit the fire, and turn the key, the engine idle moment to about 1500 turn, and then down to 500 rpm, followed by the flame. When the call is made, the engine can only emit jitter. Cleaning the throttle, opened less than half a day there can not hit the fire phenomenon. What is the reason for that?
    A: The reporter after consultation, the technician that is likely to be the problem of idle control valve. More than ten thousand kilometers of the car, if you often use the "high block low speed" driving, it is easy to cause throttle, idling valve and so on. If this is the case, it is recommended to change the driving method, driving as much as possible to keep the engine speed above 2000 rpm.
    There are technicians suggest that Mr. Zhou pay attention to the problem of oil, because poor fuel may also be the case, and many maintenance technicians rarely take this into account. Proposed Mr. Zhou to check the car's fuel system, first of all fuel to meet the requirements (for a box of oil, for a gas station to try), if there is improvement, then the next step is necessary to clean the nozzle.
