Solution

1. Preparation

Gather tools and necessary parts.
Disconnect the vehicle battery to ensure safety during repairs.

2. Inspect and Clean Throttle Body

Tools Required: Socket set, throttle body cleaner, clean rags.
Remove the air intake duct connected to the throttle body.
Use the throttle body cleaner to spray and clean the throttle valve and surrounding areas.
Wipe down with clean rags to remove carbon buildup.
Reattach the air intake duct securely.

3. Replace Fuel Filter

Tools Required: Wrench set, fuel line disconnect tool, rags.
Locate the fuel filter, typically along the fuel line under the vehicle or in the engine bay.
Use the fuel line disconnect tool to relieve pressure and disconnect the fuel lines.
Remove the old fuel filter and install the new one, ensuring correct orientation.
Reconnect fuel lines and check for leaks.

4. Inspect and Replace Spark Plugs

Tools Required: Socket set, torque wrench, gap gauge.
Remove the ignition coil cover to access spark plugs.
Use a socket to remove the old spark plugs. Inspect for wear or damage.
Install new spark plugs, ensuring they are gapped correctly to manufacturer specifications.
Torque spark plugs to the specified value (usually around 13-15 lb-ft).
Reattach the ignition coil cover.

5. Test Fuel Pump Operation

Tools Required: Fuel pressure gauge.
Locate the fuel pump relay and activate it to check if the fuel pump operates.
Connect the fuel pressure gauge to the fuel rail.
Start the engine and monitor the fuel pressure; it should be within manufacturer specifications.
If pressure is low, consider replacing the fuel pump.
