Check fuel lines for any signs of leakage or damage. Replace if necessary.
Remove and clean fuel injectors using a fuel injector cleaning kit. If they are faulty, replace them.
Reinstall all components and ensure connections are secure.

4. Adjust Tire Pressure

Use a tire pressure gauge to check each tire's pressure.
Inflate or deflate tires to the recommended pressure as specified in the owner’s manual.

5. Repair or Replace Vacuum Leaks

Locate vacuum hoses and inspect for cracks or disconnections.
Replace any damaged hoses with new ones.
Reconnect all hoses ensuring a tight fit.
