Solution

1. Preparation

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

2. Clean the Throttle Body

Remove the air intake duct connected to the throttle body using a socket set.
Spray throttle body cleaner inside the throttle body and wipe it clean with a lint-free cloth.
Reinstall the air intake duct and secure it with the appropriate fasteners.

3. Replace Air Filter

Locate the air filter housing and remove the clips or screws holding it in place.
Remove the old air filter and inspect the housing for debris.
Install a new air filter, ensuring it fits snugly, and reassemble the housing.

4. Check and Replace Fuel Filter (if necessary)

Locate the fuel filter (if applicable) and relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the fuel lines using line wrenches, being careful of fuel spillage.
Replace the old fuel filter with a new one, ensuring proper orientation and secure connections.

5. Inspect and Change Transmission Fluid (if necessary)

Locate the transmission dipstick, remove it, and check the fluid level and condition.
If the fluid is low or dirty, drain the transmission fluid from the pan and replace it with new fluid as per manufacturer specifications.
Reinstall the drain plug and refill the transmission with the appropriate fluid using a funnel.
