Solution
1. Preparation
  • Gather tools: OBD-II scanner, socket set, multimeter, fuel pressure gauge, and basic hand tools.
  • Park the vehicle on a level surface and engage the parking brake.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Inspect and Replace the Air Filter
  • Locate the air filter housing and remove the screws or clips securing it.
  • Remove the air filter and inspect it for dirt or blockages.
  • Replace with a new air filter if it is dirty or clogged.
  • Reassemble the air filter housing.
3. Fuel System Check
  • Use a fuel pressure gauge to check fuel pressure at the fuel rail.
  • If pressure is low, inspect and replace the fuel filter if it's clogged.
  • Check the fuel pump operation; replace if faulty or weak.
4. Ignition System Inspection
  • Remove the spark plugs using a socket wrench and inspect them for wear.
  • Replace spark plugs if they are worn or fouled.
  • Test ignition coils with a multimeter; replace if they do not meet specifications.
5. Exhaust System Inspection
  • Inspect the exhaust system visually for any signs of damage or blockage.
  • Use a pressure gauge to check back pressure in the exhaust; replace the catalytic converter if back pressure is too high.
6. Throttle Position Sensor Testing
  • Locate the TPS and disconnect the electrical connector.
  • Use a multimeter to test the sensor’s resistance; compare results to specifications.
  • Replace the TPS if it is out of specification.
