Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Clean Throttle Body

Remove the air intake duct connecting to the throttle body.
Use a throttle body cleaner and a soft cloth to clean the throttle plate and surrounding area.
Reattach the intake duct securely.

3. Address Fuel Pressure Issue

If fuel pressure is low, replace the fuel filter and inspect the fuel pump for proper function.
- Sub-steps:
  - Relieve fuel system pressure (consult service manual for procedures).
  - Disconnect the fuel lines using appropriate tools.
  - Replace the fuel filter and reattach lines securely.
  - If needed, replace the fuel pump by accessing it through the fuel tank or trunk area.

4. Replace Ignition Components (if necessary)

If ignition components are found faulty, replace spark plugs and coils.
- Sub-steps:
  - Remove any engine covers obstructing access to the ignition system.
  - Unscrew and remove old spark plugs using a socket wrench.
  - Install new spark plugs with the correct torque specification (usually around 13-18 lb-ft).
  - Replace ignition coils as needed, ensuring proper seating.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Clear any error codes using the OBD-II scanner.
Start the engine and let it idle for a few minutes.
