Low gas milege

Hello, typically low fuel economy can occur from improper fuel to air mixture ratios. Such information is created by the engine's processor by reading data from various sensors. If a sensor in the exhaust stream is faulty, the vehicle could continue to consume fuel wastefully. Either way, it is important to have the vehicle inspected at a qualified shop near you.
