Solution

1. Preparation

Gather tools and ensure you have a clean workspace.
Disconnect the battery to avoid electrical shock during the process.

2. Address Fuel Delivery Issues

Fuel Pump Inspection
- Locate the fuel pump fuse in the fuse box and check its condition.
- If the fuse is good, use a fuel pressure gauge to test fuel pressure at the fuel rail.
- Replace the fuel pump if pressure is below manufacturer specifications (typically around 50-60 psi for most vehicles).
- Tools Required: Fuel pressure gauge.
Fuel Filter Replacement
- Locate the fuel filter (usually near the fuel tank).
- Relieve fuel pressure by removing the fuel pump fuse and running the engine until it stalls.
- Disconnect the fuel lines from the filter and replace it with a new one.
- Reconnect fuel lines and reinsert the fuel pump fuse.
- Tools Required: Wrenches, new fuel filter.

3. Inspect and Clean the Throttle Body

Throttle Body Cleaning
- Remove the air intake duct to access the throttle body.
- Use throttle body cleaner and a soft cloth to clean carbon buildup inside the throttle body.
- Ensure the throttle plate moves freely and is not sticking.
- Reassemble the air intake duct securely.
- Tools Required: Throttle body cleaner, cloth.

4. Check and Replace the Spark Plugs (if necessary)

Spark Plug Inspection
- Remove the ignition coil covers to access the spark plugs.
- Inspect the plugs for wear, fouling, or damage.
- Replace with OEM spark plugs if they are worn or damaged.
- Torque plugs to manufacturer specifications (usually around 13-18 ft-lbs).
- Tools Required: Spark plug socket, torque wrench.
