Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Ensure the vehicle is parked on a level surface with the engine off.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Inspect and Clean the Air Intake System
  • Remove the air cleaner assembly.
  • Check for debris or blockages in the air intake hose.
  • Clean the MAF sensor using MAF cleaner, ensuring no residue is left behind.
  • Reassemble the air intake components securely.
3. Check and Replace Fuel Filter
  • Locate the fuel filter, typically near the fuel tank or along the fuel line.
  • Relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
  • Disconnect the fuel lines from the filter, taking care to catch any spillage.
  • Replace with a new fuel filter, ensuring correct orientation.
  • Reconnect fuel lines and replace the fuse.
4. Inspect and Replace Ignition Components
  • Remove the engine cover if necessary to access the ignition coils.
  • Check the condition of spark plugs for wear or deposits.
  • Replace spark plugs if they are worn or fouled (torque to manufacturer specifications).
  • Test and replace faulty ignition coils as needed.
5. Test and Replace Throttle Position Sensor
  • Locate the TPS on the throttle body.
  • Disconnect the electrical connector and use a multimeter to test the resistance.
  • If the readings are out of specification, replace the TPS.
  • Reassemble and reconnect the electrical connector.
