Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Address Fuel Delivery Issues

Check Fuel Filter:
- Locate the fuel filter, usually along the fuel line.
- If clogged, replace with a new filter.
- Tools required: Wrench set, fuel line removal tool.
Replace Fuel Pump (if necessary):
- Disconnect the battery.
- Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
- Remove fuel tank (if applicable) to access the fuel pump.
- Replace the fuel pump and reassemble.
- Tools required: Socket set, jack stands, fuel line disconnect tool.

3. Clean or Replace Throttle Body

Remove Throttle Body:
- Disconnect the battery.
- Remove the air intake duct connected to the throttle body.
- Unbolt and disconnect any electrical connectors.
- Remove the throttle body from the intake manifold.
- Tools required: Socket set, screwdriver.
Clean Throttle Body:
- Use throttle body cleaner and a soft cloth to clean the interior surface.
- Ensure the throttle plate moves freely.
- Reinstall the throttle body and reconnect all components.

4. Inspect and Replace Spark Plugs

Remove Old Spark Plugs:
- Disconnect the ignition coil wires.
- Use a spark plug socket to remove the spark plugs.
- Inspect for wear, carbon buildup, or damage.
- Tools required: Spark plug socket, torque wrench.
Install New Spark Plugs:
- Gap the new spark plugs to manufacturer specifications.
- Install and torque to the specified value (usually around 13 lb-ft).
- Reconnect the ignition coils.
