Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Clean or Replace Air Filter

Remove the air filter housing cover using a socket set.
Inspect the air filter; if dirty, replace it with a new one.
Reinstall the air filter housing cover and secure it properly.

3. Clean Throttle Body

Remove the intake duct connected to the throttle body.
Use a throttle body cleaner and a soft cloth to clean the inside of the throttle body.
Open the throttle plate manually (if possible) to clean the back side.
Reconnect the intake duct securely.

4. Replace Spark Plugs

Remove the ignition coil(s) using a socket set.
Extract the old spark plugs using a spark plug socket.
Inspect and replace with new spark plugs, ensuring they are gapped correctly according to manufacturer specifications.
Reinstall ignition coil(s) and ensure they are seated properly.

5. Check and Adjust Fuel Pressure

Connect the fuel pressure gauge to the fuel rail test port.
Start the engine and monitor fuel pressure; it should be within specifications for the model.
If pressure is low, inspect the fuel pump and fuel filter for issues.

6. Inspect Transmission Fluid

Locate the transmission dipstick (if applicable) and check fluid level and color.
If low, add the recommended transmission fluid.
If fluid is burnt or dirty, consider a transmission fluid change.
