Your mass airflow sensor (known as MAF) needs to be replaced.

Your O2 Sensor (Oxygen Sensor) needs to be replaced. The Oxygen sensor, known as the O2 sensor, measures the dump of oxygen in your exhaust system. If there is excess oxygen in your exhaust system, fuel burns faster and your vehicle will be less meager when it comes to fuel economy.
Issues with each aftermarket items. An aftermarket alarm, exhaust or further item can wreak havoc on your 2012 Chevy Malibu if it’s not installed correctly.

Check Engine Light Service 2012 Chevy Malibu

What do you do when you’re driving along in your Chevy Malibu and suddenly, a yellow light illuminates on your dash and says "Check Engine". If you’re like most Chevy owners, your heart sinks a little because you have little idea about what that light is trying to tell you or how you should react. The fear of the unknown (or the cost of the unknown) can be just as stressful. But take a deep breath and realize the light coming on doesn’t mean you have to pull the car over to the side of the road and call a tow truck, but it is recommended that you get your 2012 Chevy Malibu checked as soon as possible. Ignoring that warning could end up causing major damage to expensive engine components.

When your 2012 Chevy Malibu's ECM (electronic control module), which is the vehicle's onboard computer, finds a problem in the electronic control system that it can’t correct, a computer turns on your check engine light. This amber or yellow light is typically labeled “check engine” or “service engine soon”, or the light may be nothing more than a picture of an engine, or a picture of the engine with the word “check.”

When the light turns on, the ECM stores an engine code or “trouble code” in its memory that identifies as the issue, whether it's a sensor or a failing engine part. This code is read with an electronic scan tool that is used by our Chevy auto repair mechanics at Hare Chevrolet. There are also a number of relatively inexpensive code readers that are designed for do-it-yourselfers, should you choose that route too. While this code will tell you the issue that is detected, a true diagnosis still requires an experienced professional to determine the issue and repair it.
