Solution

1. Preparation

Gather tools and parts before starting.
Disconnect the battery to prevent electrical shorts.
Ensure the vehicle is on a level surface and secured with jack stands if elevated.

2. Inspect and Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the air filter and inspect it for dirt or damage.
Replace with a new air filter if necessary.
Reassemble the housing cover.

3. Check and Replace Fuel Filter

Locate the fuel filter (may vary by model).
Relieve fuel pressure from the system by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect fuel lines from the filter using appropriate line disconnect tools.
Replace the old fuel filter with a new one, ensuring proper orientation.
Reconnect the fuel lines and fuse.

4. Clean Throttle Body

Remove the air intake duct to access the throttle body.
Use throttle body cleaner and a soft cloth to remove carbon buildup inside the throttle body.
Ensure the throttle plate moves freely and is not sticking.
Reattach the air intake duct securely.

5. Inspect and Replace Spark Plugs

Remove the ignition coil covers if applicable.
Use a spark plug socket to remove each spark plug.
Check for wear, carbon buildup, or damage, and replace with OEM-spec spark plugs.
Reinstall coils and covers.
