Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool before starting work.

2. Clean or Replace Air Filter

Remove the air intake cover.
Take out the air filter and inspect it for dirt or damage.
If dirty, clean it or replace it with a new one.
Reinstall the air intake cover securely.

3. Check and Replace Fuel Filter (if applicable)

Locate the fuel filter along the fuel line.
Use appropriate tools to disconnect the fuel lines (be cautious of fuel spills).
Remove the old fuel filter and install the new one in the correct orientation.
Reconnect fuel lines and check for leaks.

4. Clean Throttle Body

Remove the intake hose connected to the throttle body.
Spray throttle body cleaner onto a clean cloth and wipe the throttle plate and body.
Ensure not to damage any components.
Reinstall the intake hose securely.

5. Inspect and Replace Spark Plugs

Remove the engine cover if necessary to access spark plugs.
Use a socket set to carefully remove each spark plug.
Inspect for wear or damage; replace if necessary.
Torque new spark plugs to manufacturer specifications (usually around 13-15 lb-ft).

6. Reconnect Battery and Test Drive

Reconnect the negative battery terminal.
Start the engine and let it idle for a few minutes.
Test drive the vehicle to ensure that power during acceleration has returned to normal.
