Solution

1. Preparation

Tools Required: OBD-II scanner, fuel pressure gauge, socket set, multimeter, torque wrench, cleaning supplies.
Disconnect the battery to prevent electrical shorts during repairs.

2. Addressing Error Codes

Retrieve and document any error codes from the OBD-II scanner.
Research the codes to identify potential causes (e.g., faulty sensors, electrical issues).

3. Inspect Fuel System

Tools Required: Fuel pressure gauge.
- Locate the fuel pressure test port on the fuel rail.
- Connect the fuel pressure gauge and turn the ignition key to the "On" position without starting the engine.
- Record the pressure reading; compare it to manufacturer specifications.
- If pressure is low, inspect the fuel pump, relay, and filter for issues. Replace any faulty components.

4. Clean Throttle Body

Tools Required: Throttle body cleaner, soft brush, rags.
- Remove the air intake duct from the throttle body.
- Spray throttle body cleaner into the throttle body and scrub gently with a soft brush to remove carbon buildup.
- Wipe clean with a rag and reassemble the intake.

5. Check for Vacuum Leaks

Inspect all vacuum hoses and intake manifold gaskets for signs of wear or damage.
Replace any damaged hoses or gaskets as necessary to ensure a tight seal.

6. Reassemble and Test

Reconnect the battery and ensure all components are securely fastened.
Clear any error codes using the OBD-II scanner and perform a test drive to check for improvement.
