Solution

1. Preparation

Gather tools and parts needed for repairs.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is parked on a flat, stable surface and secure it with wheel chocks.

2. Fuel System Inspection

Remove the fuel pump relay: Locate the fuel pump relay in the fuse box and remove it.
Test fuel pressure: Attach a fuel pressure gauge to the fuel rail. Start the engine and check the pressure readings against manufacturer specifications.
Replace the fuel filter if needed: Disconnect the fuel lines, remove the old filter, and install a new one ensuring proper orientation.

3. Electrical System Check

Test the battery: Use a multimeter to check the battery voltage. It should read between 12.4V and 12.7V when the engine is off.
Inspect the alternator: Start the vehicle and check voltage at the battery terminals. It should read between 13.7V and 14.7V with the engine running.
Replace any faulty components: If either the battery or alternator is out of spec, replace accordingly.

4. Air Intake and Throttle Body Cleaning

Remove the air intake duct: Unscrew any clamps and disconnect sensors to access the throttle body.
Clean the throttle body: Use throttle body cleaner and a soft cloth to remove carbon deposits. Ensure the throttle plate moves freely.
Reassemble the intake duct: Reconnect all components and ensure that all clamps are tightened securely.
