Ma San's accelerator has been used for seven years. Is it time to replace it?

There are many reasons for the high fuel consumption of automobiles, such as spark plugs, high-voltage lines, oxygen sensors and throttles. In addition, the level of fuel consumption is also related to road conditions, environment, driving habits, climate and other factors! It is recommended to go to the garage for inspection. Do not change the throttle as long as it is normal. If it's not clean, clean it!
