Solution

1. Preparation

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

2. Clean or Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the air filter and inspect it for dirt or damage.
- If dirty: Clean it or replace it with a new one.
Reinstall the air filter and housing cover, securing it properly.

3. Fuel System Inspection

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position without starting the engine.
Read the pressure gauge; it should be within the manufacturer's specifications (typically around 50-60 psi for most Camry models).
- If low: Check for clogged fuel filter or failing fuel pump.
If necessary, replace the fuel filter or pump.

4. Throttle Body Cleaning

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle body.
Open the throttle plate manually and clean behind it.
Allow the cleaner to dry, then reattach the intake duct.

5. Ignition System Check

Remove the spark plugs using a spark plug socket.
Inspect each spark plug for wear or deposits; replace if necessary.
Check ignition coils for any signs of damage or failure; replace if needed.
Reinstall the spark plugs and torque them to the manufacturer's specifications (typically around 13-15 lb-ft).
