Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the engine turned off.
Disconnect the battery to prevent any electrical issues during repair.

2. Fuel System Inspection

Sub-steps:
1. Remove the fuel pressure test port cap on the fuel rail.
2. Connect a fuel pressure gauge to the test port.
3. Turn the ignition to the "On" position (do not start the engine) and check the fuel pressure; it should be within manufacturer specifications (typically 50-60 psi).
4. If pressure is low, inspect the fuel pump and fuel filter for blockages or failures.
5. Replace the fuel filter if it hasn’t been changed in the last 30,000 miles.

3. Ignition System Inspection

Sub-steps:
1. Remove the ignition coil cover and disconnect the ignition coils.
2. Inspect the spark plugs for wear or carbon fouling; replace if necessary (should be gapped correctly as per specifications).
3. Test ignition coils with a multimeter; replace any coil that shows readings outside the specifications.
4. Reassemble the ignition components once inspections are complete.

4. Throttle Position Sensor Check

Sub-steps:
1. Locate the throttle position sensor (TPS) on the throttle body.
2. Disconnect the TPS connector and use a multimeter to measure the voltage output while moving the throttle plate.
3. Compare the readings to the manufacturer’s specifications; replace the sensor if readings are out of range.
4. Reconnect the TPS and ensure it is securely fastened.
