Clean fuel injectors and a properly functioning fuel pump are essential for efficient fuel delivery to the engine. Regularly inspecting the fuel system can prevent issues such as rough idling and poor acceleration.

6. Check the Battery

A reliable battery is crucial for powering the electrical components of your Jeep. Inspect the battery terminals for corrosion and ensure a secure connection. Keeping your battery in good condition can prevent starting issues and electrical malfunctions.
