Solution

1. Preparation

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

2. Fuel System Inspection

1.1 Connect a fuel pressure gauge to the fuel rail.
1.2 Turn the ignition to the "ON" position without starting the engine and check the pressure reading. It should match the manufacturer’s specifications (usually around 30-40 psi).
1.3 If pressure is low, inspect the fuel pump and fuel filter. Replace if necessary.

3. Ignition System Repair

2.1 Remove the ignition coil(s) and inspect for damage or wear.
2.2 Replace any faulty ignition coils.
2.3 Remove spark plugs and check for fouling or excessive wear. Replace if necessary, ensuring the gap is set to manufacturer specifications.

4. Air Intake System Maintenance

3.1 Inspect the air filter and replace if it is dirty or clogged.
3.2 Check for any cracks or loose connections in the air intake hoses. Repair or replace as necessary.

5. Vacuum Leak Inspection

4.1 Use a smoke machine or carburetor cleaner to check for vacuum leaks around the intake manifold.
4.2 If leaks are found, replace gaskets or hoses as needed.
