Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Fuel System Inspection

Tools Required: Fuel pressure gauge, wrench set, safety goggles
Remove the fuel line at the engine and connect the fuel pressure gauge.
Turn the ignition to the 'ON' position (do not start) to check fuel pressure.
If pressure is below specifications, replace the fuel pump.

3. Electrical System Check

Tools Required: Multimeter
Use a multimeter to check battery voltage; it should be around 12.6 volts when the engine is off.
Inspect and tighten any loose connections on the battery and starter.
If voltage is low, charge or replace the battery as needed.

4. Ignition System Repair

Tools Required: Socket set, torque wrench
Remove and inspect spark plugs for wear; replace if necessary.
Check ignition coils for proper function; replace any faulty coils.
Reinstall spark plugs and coils, ensuring proper torque specifications are followed.

5. Throttle Body Cleaning

Tools Required: Throttle body cleaner, soft brush
Remove the throttle body from the intake manifold.
Clean the throttle plate and surrounding areas with throttle body cleaner.
Reinstall the throttle body and reconnect all hoses and electrical connectors.
