Toyota Corolla Throttle Body Unit

Corolla has been a best-seller for Toyota for decades, and no matter what generation you drive, you enjoy top-of-the-line fuel economy. That is, unless there's a problem with the engine. If your Toyota Corolla throttle body unit is malfunctioning, your miles per gallon aren't what they should be, so rely on AutoZone for a trusty replacement.

A throttle body unit for Toyota Corolla affects the efficiency of your engine because it's the component that allows air into the combustion chamber. If the airflow is limited or blocked by build-up, too much fuel is getting fed to the engine, and it's probably causing flooding, which leads to stalling out or creeping when you hit the gas. Order one of AutoZone's Corolla throttle body units online and choose Same Day Store Pickup for added convenience. Or, take your pick from our in-store assortment and enjoy free battery charging and engine diagnostic testing at the same time.
