Solution

1. Preparation

Gather tools and parts needed for repair.
Disconnect the battery to prevent electrical shocks.

2. Fuel System Inspection

Tools Required: Fuel pressure gauge, multimeter, basic hand tools.
Check the fuel pressure at the fuel rail using a fuel pressure gauge to ensure it meets manufacturer specifications (typically around 30-50 psi).
- If pressure is low, inspect the fuel pump and fuel filter.
- Replace the fuel filter if it is clogged.
- If the fuel pump is faulty, replace it.

3. Ignition System Inspection

Tools Required: Spark plug socket, multimeter.
Remove spark plugs and inspect for wear or damage.
- Replace any worn or damaged spark plugs.
Test ignition coils using a multimeter to ensure they are functioning correctly.
- Replace any faulty ignition coils.

4. Air Intake Inspection

Tools Required: Basic hand tools.
Inspect the air filter; replace if dirty or clogged.
Check for any leaks in the air intake ducting and ensure all connections are secure.

5. Vacuum Leak Check

Tools Required: Smoke machine (optional), basic hand tools.
Use a smoke machine to detect vacuum leaks, or spray a light mist of water around the intake manifold and hoses while the engine is running. If the engine RPM changes, there is a leak.
- Tighten or replace any damaged hoses or gaskets.
