Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool down before starting work.

2. Inspect and Replace the Air Filter

Remove the air filter cover using a socket set.
Take out the old air filter and inspect it for dirt and debris.
Replace with a new air filter that meets OEM specifications.
Reassemble the air filter cover and ensure it is secured.

3. Fuel System Inspection

Fuel Pressure Test:
- Connect a fuel pressure gauge to the fuel rail.
- Turn the ignition to the "ON" position (without starting) to check pressure.
- Compare readings with manufacturer specifications (usually between 30-50 PSI).
- If pressure is low, inspect the fuel pump and replace if necessary.
Fuel Injector Cleaning:
- Remove the fuel injectors from the fuel rail.
- Use a fuel injector cleaning kit to clean each injector.
- Reinstall the cleaned injectors and ensure they are properly seated.

4. Ignition System Check

Remove spark plugs using a socket set.
Inspect for wear, carbon buildup, or damage.
Replace with new spark plugs as per manufacturer specifications (usually gap to 0.030-0.035 inches).
Check ignition coils for faults and replace any defective units.

5. Throttle Body Cleaning

Remove the throttle body from the intake manifold using a socket set.
Clean the throttle body with throttle body cleaner and a soft brush.
Ensure the throttle plate operates freely and is not sticking.
Reinstall the throttle body, ensuring proper torque specifications are followed.
