1. Remove the ignition coil(s) and inspect for cracks or wear.
2. Replace any faulty ignition coils.
3. Remove and inspect spark plugs, replacing them if they show signs of wear or fouling.
4. Reinstall ignition components securely.

4. Clean the Throttle Body

Sub-steps:
1. Remove the throttle body from the intake manifold.
2. Use throttle body cleaner and a soft cloth to remove carbon buildup.
3. Inspect the throttle position sensor for proper function.
4. Reinstall the throttle body with new gaskets if necessary.

5. Check for Vacuum Leaks

Sub-steps:
1. Inspect all vacuum hoses for cracks or disconnections.
2. Replace any damaged hoses.
