Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical shock or short circuits.

2. Inspect and Clean the Throttle Body

Remove the intake duct: Use a socket set to detach the hose clamps and remove the duct.
Access the throttle body: Unbolt the throttle body using a socket wrench.
Clean the throttle body: Use throttle body cleaner and a soft cloth to remove carbon buildup.
Reinstall the throttle body: Torque the bolts to manufacturer's specifications (typically around 89 in-lbs).
Reattach the intake duct: Securely fasten the duct with hose clamps.

3. Replace Spark Plugs

Remove the ignition coil: Unclip the connector and use a socket wrench to remove the coil.
Extract old spark plugs: Use a spark plug socket to remove the old plugs from the cylinder head.
Install new spark plugs: Apply anti-seize compound to the threads, hand-tighten, and then torque to manufacturer's specification (usually 13-16 ft-lbs).
Reinstall ignition coils: Ensure they are seated properly and reconnect the electrical connectors.

4. Check and Replace Air Filter

Locate the air filter housing: Typically found near the engine, secured with clips or screws.
Remove the housing cover: Use a screwdriver or socket set to detach the cover.
Replace the air filter: Remove the old filter and install the new one, ensuring proper seating.
Reassemble the housing: Secure the cover back onto the housing.

5. Check Fuel Pressure

Locate the fuel rail: Identify the fuel pressure test port on the rail.
Connect the fuel pressure gauge: Attach the gauge and turn the ignition to the "ON" position (do not start the engine).
Read the pressure: Compare the reading to manufacturer specifications (typically around 40-50 psi).
Replace fuel pump if necessary: If pressure is low, consider replacing the fuel pump.
