Solution

1. Preparation

Gather tools and parts.
Disconnect the battery to ensure safety while working on the vehicle.

2. Fuel System Inspection

Fuel Pressure Test
- Connect a fuel pressure gauge to the fuel rail.
- Turn the ignition to the "On" position (do not start) and check pressure readings against manufacturer specifications.
- If pressure is low, inspect the fuel pump, filter, and lines for blockages or failures.
Fuel Filter Replacement
- If the filter is clogged, remove the old filter using a socket set.
- Install a new fuel filter, ensuring all connections are secure.

3. Ignition System Check

Spark Plug Inspection
- Remove spark plugs using a socket wrench.
- Inspect for wear or carbon buildup; replace if necessary using the correct gap specification.
Ignition Coil Testing
- Use a multimeter to test the resistance of ignition coils; replace any faulty coils.

4. Air Intake System

Air Filter Replacement
- Open the air filter housing and remove the old filter.
- Install a new air filter, ensuring it fits snugly.
Vacuum Leak Inspection
- Visually inspect all vacuum hoses connected to the intake manifold for cracks or disconnections.
- Replace any damaged hoses as needed.
