Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shock.

2. Address Fuel System Issues

Inspect Fuel Pump:
- Remove the fuel pump access panel if applicable.
- Use a multimeter to test the fuel pump voltage.
- If faulty, replace the fuel pump.
Replace Fuel Filter:
- Locate the fuel filter in the fuel line.
- Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
- Disconnect the fuel lines from the filter and remove it.
- Install a new fuel filter, ensuring proper orientation.

3. Inspect Air Intake System

Check Air Filter:
- Remove the air filter housing cover.
- Inspect the air filter for dirt and debris.
- Replace the air filter if it is clogged.
Inspect Throttle Body:
- Remove the throttle body from the intake manifold.
- Clean the throttle body with throttle body cleaner and a soft cloth.
- Reinstall the throttle body and torque the bolts to manufacturer specifications.

4. Inspect Ignition System

Check Spark Plugs:
- Remove the spark plug wires and use a socket to remove the spark plugs.
- Inspect for wear or carbon buildup; replace if necessary.
- Gap new spark plugs to manufacturer specifications before installation.
Inspect Ignition Coils:
- Using a multimeter, check the resistance of the ignition coils.
- Replace any faulty ignition coils.

5. Reconnect Battery and Clear Codes

Reconnect the battery terminals.
Use the OBD-II scanner to clear any trouble codes from the ECU.
