Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety.
Lift the vehicle and secure it on jack stands if needed.

2. Air Filter Replacement

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect the housing for debris.
Install a new air filter, ensuring it is seated properly.
Reattach the housing cover and tighten securely.

3. Fuel System Pressure Check

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the "on" position without starting the engine to check the pressure.
- Reference the vehicle's manual for the correct pressure range.
If pressure is low, inspect the fuel pump and fuel filter for clogs or failure.

4. Throttle Body Cleaning

Remove the throttle body from the intake manifold by disconnecting the necessary cables and hoses.
Use a throttle body cleaner and a soft brush to clean the interior surfaces.
Reinstall the throttle body and reconnect all components securely.

5. Transmission Fluid Inspection

Locate the transmission dipstick and check the fluid level.
If low, add the appropriate type of transmission fluid as specified in the owner's manual.
If the fluid is dark or has a burnt smell, consider a fluid change.

6. Ignition System Check

Remove the spark plugs using a spark plug socket.
Inspect plugs for wear or deposits; replace if necessary.
Test ignition coils with a multimeter to ensure they are within specifications.
