Solution

1. Preparation

Gather tools and parts needed for repair.
Disconnect the negative battery terminal to ensure safety during repairs.
Allow the engine to cool before starting any work.

2. Clean or Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the air filter and inspect it for dirt and damage.
If dirty, clean with compressed air or replace with a new air filter. Ensure the new filter is properly seated.

3. Inspect and Clean Throttle Body

Remove the intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
Reassemble the intake duct securely.

4. Check and Replace Fuel Filter (if applicable)

Locate the fuel filter (if external; some models have it integrated).
Relieve fuel pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect fuel lines and remove the old fuel filter.
Install the new filter, ensuring correct direction of flow indicated on the filter.

5. Replace Spark Plugs

Remove ignition coils from the spark plugs by unscrewing them from the engine.
Use a spark plug socket to remove old spark plugs.
Install new spark plugs, ensuring the correct gap specified in the owner's manual.
Reattach the ignition coils securely.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and allow it to idle for a few minutes.
Test drive the vehicle to assess acceleration performance.
