Solution

1. Preparation

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

2. Fuel System Inspection

• Tools Required: Fuel pressure gauge, socket set, screwdrivers.
• Check the fuel pressure at the fuel rail using the gauge.
  • If pressure is low, replace the fuel pump.
  • If clogged, replace the fuel filter.
• Ensure there are no leaks in the fuel lines.

3. Air Intake and IACV Cleaning

• Tools Required: Throttle body cleaner, brush, socket set.
• Remove the intake duct to access the throttle body.
• Clean the throttle body and the IACV with throttle body cleaner and a brush.
• Reinstall the intake duct securely.

4. TPS Testing and Replacement

• Tools Required: Multimeter, socket set.
• Disconnect the TPS connector.
• Use a multimeter to measure the voltage at the TPS.
  • If the readings are outside the manufacturer’s specifications, replace the TPS.
• Reconnect the TPS connector and ensure it is securely fastened.

5. Ignition System Inspection

• Tools Required: Spark plug socket, multimeter.
• Remove spark plugs and inspect them for wear or carbon buildup.
• Replace spark plugs if they are worn or fouled.
