Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, fuel pressure gauge, multimeter.
Disconnect the battery before starting any electrical work to ensure safety.

2. Air Filter Inspection

Locate the air filter housing under the hood.
Remove the clips or screws securing the housing and take out the air filter.
Inspect the filter for dirt and debris; replace if necessary.
Reinstall the air filter and secure the housing.

3. Fuel System Check

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition key to the "on" position without starting the engine; note the pressure reading.
Compare the reading with the manufacturer’s specifications (typically around 40-50 psi for Camry).
If pressure is low, inspect the fuel pump and replace the fuel filter if clogged.

4. Throttle Body Cleaning

Remove the intake duct connected to the throttle body.
Use throttle body cleaner and a soft cloth to remove carbon deposits from the throttle plate and surrounding areas.
Reinstall the intake duct securely.

5. Spark Plug Inspection

Remove the ignition coils or spark plug wires using a socket set.
Extract the spark plugs and inspect for wear, carbon buildup, or damage.
Replace any faulty spark plugs with new ones, ensuring they are properly gapped.
Reinstall the ignition coils or wires.

6. Transmission Fluid Check

Locate the transmission dipstick and remove it.
Wipe it clean, reinsert, and then remove it again to check fluid level and condition.
If fluid is low or burnt, perform a transmission fluid change according to manufacturer specifications.
