Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Inspect and Clean the Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to remove carbon deposits from the throttle body.
Reattach the air intake duct securely.

3. Check and Replace Fuel Filter

Locate the fuel filter (usually along the fuel line).
Relieve fuel pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines from the filter using a line removal tool.
Remove the old fuel filter and install the new filter, ensuring correct orientation.
Reconnect fuel lines and replace the fuel pump fuse.

4. Replace Spark Plugs

Remove the ignition coil or spark plug wires as needed.
Use a spark plug socket to remove old spark plugs.
Install new spark plugs, ensuring they are torqued to the manufacturer's specifications (typically around 13-15 ft-lbs).
Reattach ignition coils or spark plug wires securely.

5. Test Fuel Pressure

Connect a fuel pressure gauge to the fuel rail.
Start the engine and check that fuel pressure is within the manufacturer's specified range (typically 40-60 psi).
Replace the fuel pump if pressure is inadequate.
