Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety while working on the vehicle.
Allow the engine to cool down before starting any work.

2. Clean or Replace Throttle Body

Remove the air intake duct from the throttle body using a socket set.
Clean the throttle body with throttle body cleaner and a soft cloth to remove carbon deposits.
If the throttle body is damaged or excessively worn, replace it with a new unit.

3. Replace Air Filter

Locate the air filter housing and unscrew the retaining clips or screws.
Remove the old air filter and inspect the housing for debris or blockages.
Install a new air filter, ensuring it seats properly in the housing before securing it.

4. Check and Replace Fuel Filter (if applicable)

Locate the fuel filter, which may be in-line or part of the fuel pump module.
Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.
Disconnect the fuel lines (use caution due to residual fuel) and replace the old filter with a new one.
Reconnect the fuel lines and relay.

5. Inspect Transmission Fluid

Remove the transmission dipstick and check fluid level; add fluid if low.
If fluid appears dark or burnt, consider a transmission fluid change.
Use a torque wrench to properly secure the dipstick back in place.
