How do you reset the throttle body on a Chevy Malibu?

To reset the throttle body on a Chevy Malibu, you can follow these steps:
1. Start by cleaning or replacing the throttle body. This is important because after cleaning or replacing the throttle body, your car needs to go through a “re-learning” process to bring the idle back down.
2. After cleaning or replacing the throttle body, you may see a check engine light. Scan for codes and if you get throttle body related codes, clear them.
3. If the idle speed is still off, drive the vehicle at speeds above 45 mph and operate several acceleration and deceleration cycles.
It’s worth noting that the throttle body relearn procedure may require a compatible scan tool plugged into your vehicle. This scan tool should be able to perform functions and relearns.
Please keep in mind that these steps are general guidelines, and it’s always a good idea to consult the specific vehicle’s manual or reach out to a professional mechanic for accurate instructions tailored to your Chevy Malibu model.
