Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Clean Fuel System

Sub-steps:
1. Remove the fuel pump relay from the fuse box.
2. Relieve fuel system pressure by loosening the fuel filler cap.
3. Check the fuel filter for clogs; replace if necessary.
4. Use a fuel pressure gauge to test fuel pressure against manufacturer specifications.
5. If low, inspect the fuel pump for proper operation; replace if faulty.

3. Examine Air Intake and Throttle Body

Sub-steps:
1. Remove the air intake duct to access the throttle body.
2. Inspect the throttle body for dirt and carbon buildup; clean using throttle body cleaner and a soft brush.
3. Reassemble the air intake duct and ensure all connections are tight.

4. Check Ignition System

Sub-steps:
1. Remove spark plug wires and inspect for damage or corrosion.
2. Replace worn or fouled spark plugs with new ones, ensuring proper gap settings.
3. Test the ignition coils with a multimeter; replace if outside specification.

5. Battery and Alternator Test

Sub-steps:
1. Use a multimeter to check the battery voltage; it should read between 12.4V and 12.7V.
2. Start the engine and check the voltage again; it should be between 13.7V and 14.7V.
3. If voltage readings are low, replace the battery or alternator as necessary.
