Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to ensure safety.
Allow the engine to cool before starting work.

2. Clean or Replace the Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft brush to clean the inside of the throttle body.
Inspect the throttle position sensor (TPS) for proper function; replace if necessary.
Reconnect the air intake duct securely.

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 for dirt or damage.
Install a new air filter, ensuring it fits snugly in the housing.
Re-secure the housing with clips or screws.

4. Test and Repair Fuel System

Connect the fuel pressure gauge to the fuel rail and turn the ignition to the "ON" position (do not start the engine).
Check the fuel pressure against the manufacturer's specifications; replace the fuel pump if pressure is low.
Inspect fuel injectors for clogs; clean or replace as necessary.

5. Check Ignition System

Remove spark plugs and inspect for wear or fouling.
Replace spark plugs if they are worn or damaged and ensure proper gap.
Test ignition coils with a multimeter; replace faulty coils.

6. Transmission Fluid Service

Check the transmission fluid level using the dipstick.
If low, add the appropriate type of transmission fluid as specified in the owner's manual.
If fluid is dark or burnt, consider a transmission fluid change.
