Solution

1. Preparation

Gather tools and parts.
Disconnect the battery to ensure safety while working on electrical systems.
Allow the engine to cool before starting any work.

2. Addressing Fuel System Issues

Step 2.1: Inspect the fuel filter for clogs.
- If clogged, replace the fuel filter with a new one.
Step 2.2: Test fuel pressure with a fuel pressure gauge.
- If pressure is below specifications, replace the fuel pump.

3. Repairing the Ignition System

Step 3.1: Remove the engine cover to access the ignition components.
Step 3.2: Inspect spark plugs for wear and carbon buildup.
- Replace spark plugs if they are worn or fouled.
Step 3.3: Check ignition coils for functionality using a multimeter.
- Replace any faulty ignition coils.

4. Air Intake System Inspection

Step 4.1: Remove the air intake duct.
Step 4.2: Inspect the throttle body for carbon buildup.
- Clean the throttle body with throttle body cleaner and a soft brush.
Step 4.3: Check for vacuum leaks by inspecting hoses and gaskets.
- Replace any damaged hoses or gaskets.

5. Battery and Alternator Testing

Step 5.1: Use a multimeter to test the battery voltage; it should read around 12.6 volts.
Step 5.2: Start the engine and check the alternator output; it should read between 13.7 to 14.7 volts.
- Replace the battery or alternator if readings are outside these ranges.
