Solution

1. Preparation

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

2. Throttle Body Cleaning

1. Remove the air intake duct from the throttle body using a socket set.
2. Clean the throttle body using throttle body cleaner and a soft cloth, ensuring to remove carbon deposits.
3. Reinstall the air intake duct securely.

3. Fuel System Inspection

1. Locate the fuel pressure test port on the fuel rail.
2. Attach the fuel pressure gauge and turn the ignition to the "ON" position (without starting the engine) to check fuel pressure.
3. If pressure is below specifications (refer to service manual), replace the fuel filter and inspect the fuel pump.
4. Reconnect the fuel pressure test port after testing.

4. Transmission Fluid Check

1. Identify the transmission dipstick or fill plug.
2. Check the fluid level and condition; if low or discolored, replace the fluid.
3. If necessary, drain and replace the transmission fluid and filter according to manufacturer specifications.

5. Accelerator Pedal Position Sensor Testing

1. Locate the accelerator pedal position sensor.
2. Use a multimeter to measure voltage output while slowly pressing the accelerator pedal.
3. If readings are outside specifications, replace the sensor.
