Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, fuel pressure gauge, and cleaning supplies.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts or shocks.

2. Fuel System Inspection

Check Fuel Pressure:
- Connect the fuel pressure gauge to the fuel rail test port.
- Turn the ignition to the "ON" position (do not start) and read the pressure. It should match specifications (usually between 30-50 PSI).
Inspect Fuel Pump Operation:
- Reconnect the battery and listen for the fuel pump priming when the ignition is turned on.
- If no sound is heard, test the fuel pump relay and wiring.
Replace Fuel Filter:
- If clogged, locate the filter and remove it using a socket set.
- Install a new filter, ensuring correct orientation.

3. Ignition System Repair

Inspect and Replace Spark Plugs:
- Remove the ignition coils using a socket set.
- Extract the spark plugs with a spark plug socket and inspect for wear.
- Replace with OEM spark plugs, tightening to proper torque (usually around 13-15 ft-lbs).
Check Ignition Coils:
- Use a multimeter to test each coil's resistance.
- Replace any faulty coils.

4. Throttle Body Cleaning

Remove Throttle Body:
- Disconnect the air intake hose and throttle body electrical connector.
- Unbolt the throttle body from the intake manifold.
Clean the Throttle Body:
- Use throttle body cleaner and a soft cloth to remove carbon buildup.
- Reassemble the throttle body and reconnect all hoses and connectors.
