Solution

1. Preparation

Gather tools and parts necessary for repairs.
Disconnect the battery to ensure safety while working on electrical components.

2. Addressing Faulty Airflow

Inspect Air Filter:
- Remove the air filter housing cover using a socket set.
- Replace the air filter if it is dirty or clogged.
Clean Throttle Body:
- Remove the throttle body by disconnecting the throttle linkage and electrical connector.
- Use throttle body cleaner and a soft brush to clean the inside of the throttle body.
- Reinstall the throttle body and reconnect all components.

3. Fuel System Inspection

Check Fuel Pressure:
- Connect a fuel pressure gauge to the fuel rail.
- Turn the ignition to the "ON" position without starting the engine and check the pressure.
- If pressure is low, replace the fuel pump and filter as needed.

4. Ignition System Repair

Inspect and Replace Spark Plugs and Coils:
- Remove the engine cover if necessary.
- Disconnect the ignition coils and remove them using a socket set.
- Replace any faulty ignition coils and worn spark plugs.
- Reinstall all components and ensure tight connections.

5. Battery and Alternator Check

Test Electrical System:
- Use a multimeter to check the battery voltage (should be around 12.6 volts).
- Start the engine and check the alternator voltage (should be between 13.7 to 14.7 volts).
- Replace the battery or alternator if readings are outside of this range.
