Solution

1. Preparation

Gather tools and materials.
Disconnect the battery to ensure safety while working on electrical components.

Tools Required:

OBD-II scanner
Fuel pressure gauge
Socket set
Screwdriver set
Cleaning solvent for throttle body

2. Address Fuel Delivery Issues

Check Fuel Pressure
- Connect the fuel pressure gauge to the fuel rail.
- Turn the ignition to the "on" position (do not start) and check if the pressure meets manufacturer specifications (usually around 50-60 psi).
- If low, inspect the fuel pump and fuel filter for clogs or failures.
Inspect and Replace Fuel Filter (if necessary)
- Locate the fuel filter; refer to the service manual for the exact location.
- Disconnect the fuel lines, ensuring to relieve pressure beforehand.
- Replace the fuel filter with a new one and reconnect the lines.

3. Clean the Throttle Body

Remove the Throttle Body
- Disconnect the air intake hose and any electrical connectors.
- Remove the throttle body mounting bolts using a socket set.
- Carefully detach the throttle body from the intake manifold.
Clean the Throttle Body
- Spray throttle body cleaner onto a clean rag or directly into the throttle body.
- Wipe away carbon buildup, ensuring the throttle plate moves freely.
- Reinstall the throttle body and reconnect all hoses and connectors.

4. Inspect and Replace Spark Plugs (if necessary)

Remove Spark Plugs
- Disconnect the ignition coils by unclipping them and removing the retaining bolts.
- Use a socket set to remove the spark plugs from the cylinder head.
Install New Spark Plugs
- Check the gap on the new spark plugs to ensure it meets specifications.
- Install the new spark plugs and torque them to the manufacturer's specifications (usually around 13-20 lb-ft).
- Reconnect the ignition coils.
