Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface and the engine is cool.
  • Disconnect the battery to ensure safety while working on electrical components.
2. Clean the Throttle Body
  • Remove the air intake duct connected to the throttle body using a socket set.
  • Use throttle body cleaner and a soft cloth to clean the inside of the throttle body thoroughly.
  • Ensure the throttle plate is free to move and operates smoothly.
  • Reassemble the air intake duct and reconnect any sensors.
3. Inspect and Replace Spark Plugs
  • Remove the ignition coil cover and disconnect the ignition coils.
  • Unscrew and remove the old spark plugs using a spark plug socket.
  • Inspect the spark plugs for wear and replace them if necessary (use OEM or equivalent).
  • Reinstall the ignition coils and cover.
4. Check Fuel Pressure
  • Attach a fuel pressure gauge to the fuel rail Schrader valve.
  • Start the engine and monitor the fuel pressure; it should be within the manufacturer's specifications (typically around 50-60 psi).
  • If pressure is low, check the fuel pump and filter for any issues and replace as needed.
5. Transmission Fluid Check
  • Locate the transmission dipstick and pull it out, wipe clean, and reinsert it.
  • Remove the dipstick again to check the fluid level; it should be within the marked range.
  • If the fluid is low, top up with the recommended transmission fluid type (typically ATF WS for a Toyota Camry).
  • If the fluid is dark or burnt, consider a transmission fluid change.
