Solution

1. Preparation

Gather tools and parts needed for repairs.
Disconnect the battery to ensure safety while working on the vehicle.

2. Fuel System Inspection

Sub-steps:
1. Locate the fuel pressure test port on the fuel rail.
2. Connect a fuel pressure gauge to the test port.
3. Turn the ignition to the "ON" position (do not start the engine) and check the fuel pressure reading against manufacturer specifications.
4. If pressure is low, inspect the fuel pump and replace it if necessary.

3. Ignition System Repair

Sub-steps:
1. Remove the engine cover to access the ignition components.
2. Inspect spark plugs for wear and replace if they are fouled or worn out.
3. Check ignition coils for proper operation and replace any faulty coils.

4. Throttle Body Cleaning

Sub-steps:
1. Remove the air intake hose connected to the throttle body.
2. Use throttle body cleaner and a soft brush to clean the throttle body and remove carbon deposits.
3. Reinstall the air intake hose securely.

5. Check for Vacuum Leaks

Sub-steps:
1. Inspect all vacuum hoses connected to the intake manifold for cracks or disconnections.
2. Replace any damaged hoses.
3. Use a smoke machine to detect leaks if necessary.
