Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety during repairs.
Allow the engine to cool down before starting any work.

2. Fuel System Inspection

Tools Required: Fuel pressure gauge, wrench set
Remove the fuel pump fuse and start the engine to relieve fuel pressure.
Disconnect the fuel line from the fuel rail and attach the fuel pressure gauge.
Turn the ignition to the "On" position without starting the engine to check fuel pressure against specifications (typically 30-50 psi for the Camry).
If pressure is low, consider replacing the fuel pump or filter.

3. Air Intake System Cleaning

Tools Required: Screwdriver, cleaning brush, throttle body cleaner
Remove the air intake duct and inspect the air filter. Replace if it’s dirty.
Clean the throttle body using throttle body cleaner and a brush to remove any carbon deposits.
Reassemble the air intake system securely.

4. Ignition System Inspection

Tools Required: Spark plug socket, multimeter
Remove spark plugs and inspect for wear or fouling. Replace if necessary.
Test ignition coils with a multimeter to ensure they are within manufacturer specifications.
Reinstall new or tested components back into the engine.

5. Vacuum Line Check

Tools Required: Visual inspection tools, smoke machine (optional)
Inspect all vacuum lines for cracks or disconnections. Replace damaged lines.
Use a smoke machine to detect leaks if necessary.
