Why is the Tiggo 7's fuel consumption getting higher and higher?
1 Answers
The reasons for the increasing fuel consumption of the Tiggo 7 include aging spark plugs leading to incomplete combustion of gasoline, tire wear and insufficient tire pressure, and aging oxygen sensors. It could also be due to excessive carbon buildup in areas such as the throttle body, idle motor, intake valves, intake pipes, combustion chamber, spark plugs, and fuel injectors. This carbon buildup can block the idle channel, causing the idle motor to stick or exceed its adjustment range, resulting in low idle speed, unstable idle, high fuel consumption, and stalling. Summer air conditioning system check: Air conditioning malfunctions are a significant cause of high fuel consumption. Poor cooling performance forces the system to increase fan speed and lower temperature to achieve a cooling effect. Avoid frequent sudden braking: Frequent sudden braking is a primary reason for persistently high vehicle fuel consumption. While ensuring safe driving, make full use of the vehicle's inertia. Small-displacement vehicles should not use air conditioning too aggressively: For vehicles exposed to the sun, avoid turning on the air conditioning immediately after entering. First, open the windows and set the fan to a higher speed without turning on the air conditioning to expel the hot air inside. Wait until the vehicle has cooled down moderately before turning on the air conditioning.
