Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Disconnect the battery to ensure safety during repairs.
2. Clean the Throttle Body
  • Remove the air intake duct connected to the throttle body.
  • Use throttle body cleaner and a soft cloth to gently clean the throttle plate and surrounding area.
  • Reattach the air intake duct.
3. Inspect and Clean the MAF Sensor
  • Disconnect the MAF sensor connector.
  • Remove the MAF sensor from the intake manifold.
  • Use MAF sensor cleaner to spray the sensor elements; allow it to dry before reinstallation.
  • Reinstall the MAF sensor and reconnect the connector.
4. Test and Replace the TPS (if necessary)
  • Disconnect the electrical connector from the TPS.
  • Use a multimeter to measure voltage at the TPS while slowly opening the throttle. Confirm that it varies smoothly.
  • If the readings are erratic or outside specifications, remove the TPS and replace it with a new unit.
5. Check Fuel System
  • Connect a fuel pressure gauge to the fuel rail.
  • Turn the ignition key to the "ON" position without starting the engine, and check the fuel pressure. It should meet manufacturer specifications.
  • If pressure is low, inspect the fuel pump and filter for clogs or failures, and replace them if necessary.
