Solution

1. Preparation

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

2. Inspect and Clean Throttle Body

Tools Required: Throttle body cleaner, socket set, screwdriver.
Remove the air intake duct to access the throttle body.
Use throttle body cleaner to spray inside the throttle body and wipe clean with a lint-free cloth.
Ensure the throttle plate moves freely without sticking.
Reinstall the air intake duct.

3. Replace Fuel Filter (if applicable)

Tools Required: Fuel line disconnect tool, wrench set.
Locate the fuel filter and place a drain pan underneath to catch any fuel.
Disconnect the fuel lines using the fuel line disconnect tool.
Remove the old fuel filter and install the new one in the correct orientation.
Reconnect the fuel lines and check for leaks.

4. Replace Spark Plugs

Tools Required: Socket set, torque wrench, spark plug gap tool.
Remove the ignition coils by unscrewing them and pulling them out gently.
Use a socket to remove the old spark plugs and inspect for wear.
Install new spark plugs, ensuring they are gapped correctly to manufacturer specifications.
Reinstall the ignition coils and secure them properly.

5. Reconnect Battery and Test

Reconnect the battery terminals securely.
Start the engine and check for any error codes using the OBD-II scanner.
Take the vehicle for a test drive to evaluate acceleration.
