Q: Car sputtering upon acceleration.

asked by on January 13, 2016

My car sputters upon acceleration. It is also getting bad gas mileage.

There are a lot of issues that could cause the symptoms you are having, from a faulty mass air flow sensor to a clogged catalytic converter. I suggest you have your vehicle inspected by a trained mechanic, such as one from YourMechanic.
