Solution

1. Preparation

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

2. Clean the Throttle Body

Remove the air intake duct to expose the throttle body.
Use throttle body cleaner and a clean cloth to remove carbon buildup inside the throttle body.
Reattach the air intake duct securely.

3. Inspect and Replace the Air Filter

Locate the air filter housing and open it.
Remove the old air filter and inspect for dirt or damage.
Install a new, clean air filter, ensuring it fits snugly in the housing.

4. Check and Replace the Fuel Filter

Locate the fuel filter (if applicable, as some models have it integrated in the fuel pump).
If replaceable, disconnect the fuel lines while ensuring to relieve fuel pressure beforehand.
Install a new fuel filter and reconnect the fuel lines, ensuring they are secure.

5. Transmission Fluid Check

Remove the transmission dipstick and inspect the fluid for color and smell (should be red and not burnt).
If low, add the manufacturer-recommended transmission fluid.
If dirty or burnt, consider a transmission fluid change.
