Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety during the repair.
Allow the engine to cool if it has recently been running.

2. Fuel System Inspection

Tools Required: Fuel pressure gauge, socket set
Sub-steps:
1. Locate the fuel pump access panel or fuel line.
2. Connect the fuel pressure gauge to the fuel line.
3. Turn the ignition key to the "On" position (do not start the engine) to check fuel pressure. It should meet manufacturer specifications (typically around 30-60 psi).
4. If pressure is low, inspect and replace the fuel filter if clogged.
5. Test the fuel pump for functionality. Replace if faulty.

3. Ignition System Repair

Tools Required: Socket set, multimeter
Sub-steps:
1. Remove the ignition coil(s) and inspect for cracks or damage.
2. Use a multimeter to test the resistance of the ignition coils. Replace if out of specifications.
3. Check spark plugs for wear and replace if necessary, ensuring proper gap settings.
4. Reinstall all components securely.

4. Throttle Body and Vacuum Leak Inspection

Tools Required: Cleaning supplies (throttle body cleaner), screwdriver set
Sub-steps:
1. Remove the intake duct to access the throttle body.
2. Inspect the throttle body for carbon buildup and clean it using throttle body cleaner.
3. Examine all vacuum hoses for cracks or disconnections and replace any damaged hoses.
4. Reassemble the intake duct securely.
