Solution

1. Preparation

Gather all necessary tools and parts before starting.
Disconnect the negative battery terminal to ensure safety during repairs.
Ensure the vehicle is parked on a flat surface and is in the "Park" position.

2. Address Fuel System Issues

Inspect Fuel Pump:
- Locate the fuel pump relay and check for continuity using a multimeter.
- If faulty, replace the fuel pump relay.
Check Fuel Filter:
- Locate the fuel filter (usually near the fuel tank).
- Replace the fuel filter if it is clogged or has not been replaced in accordance with the maintenance schedule.

3. Inspect Ignition System

Replace Spark Plugs:
- Remove the ignition coil cover and disconnect the ignition coils.
- Remove old spark plugs using a spark plug socket and torque new plugs to manufacturer specifications (typically around 13 lb-ft).
Check Ignition Coils:
- Test each ignition coil with a multimeter for resistance; replace any that are out of specifications.

4. Clean Throttle Body

Remove Throttle Body:
- Disconnect the air intake duct and any electrical connectors.
- Unbolt the throttle body from the intake manifold and remove it.
Clean Throttle Body:
- Use throttle body cleaner and a soft cloth to clean the interior surfaces, including the throttle plate.
- Reinstall the throttle body, ensuring all gaskets are properly seated.

5. Verify Air Intake System

Inspect Air Filter:
- Remove the air filter housing and check the condition of the air filter.
- Replace if dirty or clogged.
Check for Air Leaks:
- Inspect all hoses and connections in the air intake system for signs of wear or cracks. Replace any damaged components.
