Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the battery to ensure safety while working on electrical components.
  • Allow the engine to cool down before starting work.
2. Inspect and Clean Air Intake
  • Remove the air intake duct from the throttle body.
  • Inspect the air filter; replace if it is dirty or clogged.
  • Clean the throttle body using throttle body cleaner and a soft cloth.
  • Reconnect the air intake duct securely.
3. Check Fuel System
  • Use a fuel pressure gauge to measure fuel pressure at the rail; compare it to specifications from the service manual.
  • If pressure is low, inspect the fuel filter and replace if necessary.
  • Verify fuel pump operation by listening for it to activate when the ignition is turned on.
4. Inspect Spark Plugs and Ignition Coils
  • Remove spark plugs using a socket wrench.
  • Check for wear or damage; replace if necessary with OEM specifications.
  • Test ignition coils using a multimeter; replace any faulty coils.
5. Verify Throttle Position Sensor (TPS)
  • Disconnect the TPS connector and check the resistance across the terminals using a multimeter.
  • If readings are outside specification, replace the TPS.
  • Reconnect the TPS and clear any error codes from the system.
