How is Maxima Oil High?
My car was a manual horse of 1.3 years in November 2004. At present, 83,000 kilometers (second-hand friends) have been ran. In the last three months, the air-conditioned pure urban area is estimated to have a fuel consumption of 9 or higher. The shift is generally 2000 or 2500 or so. After feeling waste oil, the throttle and injectors were cleaned, and the idle motor was cleaned. The wheels are also smooth. Now I feel it is still waste oil, and I have no idea why I went to a 4S shop to check my computer. I still said that the fuel consumption is normal! ! Finally, I changed the spark plug, preliminary observation of waste oil! ! Seeing that even the horse friend in the jar had said that he could reach 5 or 6, I was envious of death. Ask me what kind of reasons to look for? Such as water temperature sensor, oxygen sensor (like 4S shop computer test that no problem), cylinder pressure (they did not measure, by feeling that no problem) seems to have what the front of the oil control sensor and so on to me How is your idea? First, thank you! Have seen a similar situation when the rider said that the temperature sensor is finally resolved, I describe this situation should be more clear, if the expert doubts the temperature sensing problem, please give pointers, or other problems, in short, help me get some ideas ? First, thank you
Hello! Regarding your question of high fuel consumption, long-term driving in the urban areas will easily lead to the formation of carbon deposits, and driving on congested roads in urban areas will result in high fuel consumption. Therefore, not only do you have to clean the throttle, idle motor, and fuel injector, but it may also be caused by too much carbon in the intake, intake, and combustion chambers. Because of the excessive carbon deposition and fouling of the air intake passage, the cross-sectional area of the air passage changes, making it impossible for the control unit to accurately control the idle air intake amount, causing the mixture to be too rich or too lean and causing the combustion to be abnormal. In addition, if there are problems with the sensors in various parts of the engine, the engine ECU will not be able to accurately control the amount of fuel injection, such as water temperature sensors, intake pressure sensors, and oxygen sensors. In addition, if there is a problem with the carbon canister valve, this phenomenon will also occur. It is recommended that you go to the 4S shop or repair shop for on-site inspection according to the above conditions.
