Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is off and cool.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Fuel System Inspection

Sub-steps:
1. Locate the fuel pump fuse and relay in the fuse box; inspect and replace if faulty.
2. Connect a fuel pressure gauge to the fuel rail and turn the ignition on (do not start the engine). The pressure should meet manufacturer specifications (usually around 30-40 psi).
3. If pressure is low, check the fuel filter for blockages and replace it if necessary.
4. If the fuel filter is clear, inspect the fuel pump by removing it from the tank and testing it with a multimeter for proper voltage and operation.

3. Air Intake System Cleaning

Sub-steps:
1. Remove the air intake duct and inspect the air filter; replace if dirty or clogged.
2. Clean the throttle body using throttle body cleaner and a soft cloth; ensure the throttle plate moves freely.
3. Reassemble the air intake system, ensuring all clamps and hoses are secure.

4. Ignition System Inspection

Sub-steps:
1. Remove the spark plugs using a spark plug socket; inspect for wear or carbon buildup.
2. Replace spark plugs if they show signs of excessive wear or fouling.
3. Test ignition coils with a multimeter; replace any coils that do not meet resistance specifications.
4. Reinstall the spark plugs and ignition components securely.
