Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shock.

2. Fuel System Inspection

Check Fuel Pressure:
- Connect a fuel pressure gauge to the fuel rail.
- Turn the ignition to the "ON" position without starting the engine and observe the pressure reading. Compare with manufacturer specifications (typically around 40-50 psi).
- If pressure is low, replace the fuel filter or fuel pump as needed.
Inspect Fuel Injectors:
- Remove the fuel injector connectors.
- Use a multimeter to test the resistance of each injector. Replace any injectors with readings outside of manufacturer specifications.

3. Ignition System Repair

Replace Spark Plugs:
- Remove the ignition coil assemblies.
- Use a spark plug socket to remove the spark plugs and inspect their condition.
- Replace worn or fouled plugs with new ones, ensuring proper gap settings.
Test/Replace Ignition Coils:
- Use a multimeter to measure the resistance on each coil's primary and secondary windings.
- Replace any faulty ignition coils.

4. Air Intake and Filters

Inspect Air Filter:
- Remove the air filter and check for dirt and clogs. Replace if necessary.
Check for Vacuum Leaks:
- Inspect all vacuum hoses and the intake manifold for cracks or disconnections.
- Repair or replace any damaged hoses.
