Solution

1. Preparation

Gather tools and parts required for repairs.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect the housing for debris.
Install a new air filter, ensuring it fits securely, and reattach the housing cover.

3. Clean Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding areas.
Reassemble the air intake duct securely.

4. Test and Replace Fuel Filter

Locate the fuel filter; disconnect the fuel lines carefully using a line wrench.
Inspect the fuel filter for clogs; if dirty, replace it with a new one.
Reconnect the fuel lines, ensuring they are secure.

5. Inspect and Replace Transmission Fluid (if necessary)

Remove the transmission fluid pan using a socket set, allowing fluid to drain completely.
Replace the transmission filter (if applicable) and clean the pan.
Refill with the manufacturer-recommended transmission fluid according to the owner's manual specifications.
