Solution

1. Preparation

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

2. Inspect and Replace Spark Plugs

Tools Required: Socket set, torque wrench
Remove the ignition coil(s) or spark plug wires.
Use the socket wrench to remove each spark plug.
Inspect the spark plugs for wear, corrosion, or carbon buildup.
Replace with new spark plugs that meet OEM specifications.
Torque the new spark plugs to the manufacturer’s specified value (typically around 13-20 lb-ft).

3. Clean the Throttle Body

Tools Required: Throttle body cleaner, soft cloth
Remove the air intake duct to gain access to the throttle body.
Spray throttle body cleaner inside the throttle body while opening the throttle plate manually.
Wipe clean with a soft cloth to remove carbon deposits.
Reinstall the air intake duct securely.

4. Check and Replace Fuel Filter

Tools Required: Fuel line disconnect tool, wrench set
Locate the fuel filter along the fuel line.
Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
Disconnect the fuel lines from the filter using the fuel line disconnect tool.
Remove the filter and install the new one, ensuring the flow direction is correct.

5. Verify Fuel Pressure

Tools Required: Fuel pressure gauge
Reconnect the fuel pump relay and turn the ignition to the "ON" position without starting the engine.
Attach the fuel pressure gauge to the fuel rail service port.
Check that the pressure reads within the manufacturer's specified range (typically 30-40 psi for most models).
If pressure is low, inspect the fuel pump and relay for faults.
