Solution

1. Preparation

Gather necessary tools and parts before starting.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Clean the Throttle Body

Tools Required: Throttle body cleaner, soft brush, clean rags.
Remove the air intake duct to access the throttle body.
Spray throttle body cleaner into the throttle body while moving the throttle plate manually.
Use a soft brush to scrub away any buildup, then wipe clean with a rag.
Reinstall the air intake duct.

3. Test and Replace the Fuel Pump (if necessary)

Tools Required: Fuel pressure gauge, socket set, screwdriver.
Locate the fuel pump relay and remove it.
Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position (do not start) and check the pressure.
If the pressure is below the specifications (usually around 40-50 psi), replace the fuel pump.
- Disconnect the battery, relieve fuel pressure by removing the fuel pump fuse, and disconnect the fuel lines from the pump.
- Replace the fuel pump and reconnect all lines and the fuse.

4. Inspect and Repair Vacuum Lines
