Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Address Fuel Delivery Issues

Fuel Pressure Check:
- Connect the fuel pressure gauge to the fuel rail Schrader valve.
- Turn the ignition to the "On" position (do not start the engine) and check the pressure reading.
- If the pressure is below specifications (consult service manual), replace the fuel pump.
Replace Fuel Filter:
- Locate the fuel filter and relieve fuel system pressure.
- Disconnect the fuel lines and remove the filter.
- Install a new fuel filter and reconnect the lines.

3. Clean or Replace Throttle Body

Remove Throttle Body:
- Disconnect the throttle body electrical connector.
- Remove the intake duct and any hoses attached to the throttle body.
- Unbolt the throttle body from the intake manifold.
Clean or Replace:
- Use throttle body cleaner to clean the throttle plate and bore.
- If damaged, replace the throttle body with a new unit.

4. Inspect and Replace Spark Plugs

Remove Spark Plugs:
- Disconnect ignition coils and remove them.
- Use a spark plug socket to remove the spark plugs.
Inspect and Install New Spark Plugs:
- Check the gap and condition of each spark plug.
- Replace with new spark plugs that meet manufacturer specifications and torque to the recommended value.

5. Reconnect Battery and Test

Reconnect the battery terminals.
Start the engine and allow it to idle.
Monitor for any warning lights and check for improved power delivery.
