Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Replace Spark Plugs

Remove the engine cover if applicable.
Use a socket set to remove the ignition coil bolts.
Pull the ignition coils out carefully.
Remove the old spark plugs with a spark plug socket.
Install new spark plugs, ensuring they are gapped according to specifications (typically 0.043 inches for Camry).
Reinstall the ignition coils and secure them with bolts.

3. Inspect and Replace Ignition Coils (if needed)

If any ignition coils show signs of damage or wear, remove them as described above.
Install new ignition coils by reversing the removal process.

4. Check for Vacuum Leaks

Visually inspect all vacuum hoses for cracks or disconnections.
Replace any damaged hoses with new ones.

5. Verify Fuel Pressure

Attach a fuel pressure gauge to the fuel rail.
Turn the ignition on without starting the engine to check pressure.
Compare readings to manufacturer specifications (typically around 40-50 psi for most Camrys).

6. Reconnect Battery

Reconnect the negative terminal of the battery after all repairs are completed.
