Solution

1. Preparation

Tools Needed: OBD-II scanner, socket set, torque wrench, multimeter, fuel pressure gauge.
Disconnect the negative battery terminal to ensure safety.

2. Address Fuel System Issues

a. Check Fuel Pump Operation:
- Reconnect the battery and turn the ignition to the "ON" position without starting the engine. Listen for the fuel pump's operation.
b. Replace Fuel Filter:
- Locate the fuel filter and use a socket set to remove it. Install the new filter, ensuring the flow direction matches the vehicle's specifications.
c. Test Fuel Pressure:
- Use a fuel pressure gauge to check that the pressure meets manufacturer specifications. If low, consider replacing the fuel pump.

3. Clean or Replace Ignition Components

a. Inspect Spark Plugs:
- Remove spark plugs using a socket set. Check for wear and carbon buildup. Replace if necessary with OEM-spec plugs.
b. Test Ignition Coils:
- Using a multimeter, check the resistance of each ignition coil. Replace any coils that do not meet specifications.

4. Clean the Throttle Body

a. Remove Throttle Body:
- Disconnect the throttle body wiring harness and remove the throttle body using a socket set.
b. Clean:
- Use throttle body cleaner and a soft brush to remove carbon deposits. Ensure all passages are clear.
c. Reinstall:
- Reattach the throttle body, torque to manufacturer specifications, and reconnect the wiring harness.

5. Check for Vacuum Leaks

Inspect all vacuum hoses and intake gaskets for signs of wear or damage. Replace any faulty hoses or gaskets.
