Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical shorts.

2. Replace Clogged Air Filter

Remove the air intake cover using a socket set.
Take out the old air filter and inspect the air filter housing for debris.
Install a new air filter (OEM recommended) ensuring it fits snugly.
Reattach the air intake cover and secure it with screws.

3. Inspect and Replace Spark Plugs

Remove the engine cover if applicable.
Disconnect the ignition coils from the spark plugs.
Use a spark plug socket to remove the old spark plugs.
Inspect the old spark plugs for wear; replace them with new ones (OEM recommended).
Reattach the ignition coils and secure them properly.

4. Check and Replace Fuel Filter

Locate the fuel filter along the fuel line.
Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
Disconnect the fuel lines from the filter using a line disconnect tool.
Replace the old filter with a new one, ensuring correct orientation.
Reconnect the fuel lines and replace the fuel pump fuse.

5. Transmission Fluid Check and Replacement

With the engine running, check the transmission fluid level using the dipstick.
If low, add the manufacturer-recommended transmission fluid.
If the fluid is dark or burnt, consider a transmission fluid change:
- Remove the drain plug and drain the old fluid.
- Replace with new transmission fluid (follow manufacturer specifications).
- Reinstall the drain plug and check the fluid level again.
