Solution
1. Preparation
  • Gather tools and parts needed.
  • Disconnect the battery to ensure safety while working on electrical components.
  • Allow the engine to cool if it has been running.
2. Clean Throttle Body
  • Remove the intake duct connected to the throttle body.
  • Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
  • Ensure the throttle plate moves freely without obstruction.
  • Reattach the intake duct securely.
3. Inspect and Test Throttle Position Sensor (TPS)
  • Locate the TPS connected to the throttle body (usually accessible without removing the throttle body).
  • Disconnect the TPS electrical connector.
  • Using a multimeter, check the voltage output while slowly opening the throttle. Voltage should increase smoothly from 0.5V to approximately 4.5V.
  • If readings are erratic or outside the specified range, replace the TPS.
4. Check for Vacuum Leaks
  • Inspect all vacuum hoses connected to the intake manifold for cracks or disconnections.
  • Use a smoke machine or carburetor cleaner around the intake areas to detect leaks. Look for changes in engine RPM as an indicator of a leak.
  • Replace any damaged hoses or gaskets.
5. Verify Fuel Delivery
  • Use a fuel pressure gauge to check the fuel pressure at the fuel rail; it should match manufacturer specifications.
  • Inspect fuel injectors for proper operation; listen for a clicking sound and check for any fuel leaks.
  • Replace fuel filters if clogged or restricted.
