Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Check Fuel System
  1. Inspect Fuel Filter

    • Locate the fuel filter; remove it using a line wrench.
    • Replace the fuel filter if it is clogged.
    • Connect the new filter and ensure proper orientation and fittings are secure.
  2. Test Fuel Pump

    • Connect the fuel pressure gauge to the fuel rail.
    • Turn the ignition to the "On" position (do not start) and check the pressure reading; it should meet manufacturer specifications.
    • If pressure is low, replace the fuel pump.
3. Inspect Throttle Position Sensor (TPS)
  1. Remove the TPS

    • Locate the TPS on the throttle body.
    • Disconnect the electrical connector and remove the mounting screws.
  2. Test the TPS

    • Use a multimeter to check the resistance across the terminals while moving the throttle plate.
    • Replace the TPS if the readings are inconsistent or out of spec.
4. Examine Ignition Components
  1. Replace Spark Plugs

    • Remove spark plug wires and use a spark plug socket to remove each spark plug.
    • Inspect for wear; replace with OEM or equivalent plugs.
    • Reinstall spark plugs with the correct torque specification.
  2. Check Ignition Coils

    • Inspect each coil for cracks or damage.
    • Use a multimeter to test coil resistance; replace any faulty coils.
5. Reassemble and Reconnect
  • Reattach all components and connectors that were removed during the inspection process.
  • Reconnect the negative battery terminal.
