Solution

1. Preparation

Tools Needed: OBD-II scanner, multimeter, fuel pressure gauge, socket set
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Disconnect the battery to prevent electrical shock.

2. Check Fuel Pump

Sub-steps:
1. Locate the fuel pump access point (if applicable) or the fuel tank.
2. Connect the fuel pressure gauge to the fuel rail.
3. Turn the ignition key to the "on" position (do not start) and check the fuel pressure. It should be within the manufacturer's specifications (typically around 40-50 psi).
4. If pressure is low, inspect the fuel pump and replace if necessary.

3. Inspect Ignition System

Sub-steps:
1. Remove the engine cover to access the ignition coils and spark plugs.
2. Use a multimeter to check the resistance of the ignition coils; replace any that are out of specification.
3. Remove and inspect the spark plugs for wear or carbon buildup. Replace if necessary with OEM parts.
4. Reassemble all components securely.

4. Check for Vacuum Leaks

Sub-steps:
1. Visually inspect all vacuum hoses for cracks or disconnections.
2. Use carburetor cleaner or a smoke machine around the intake manifold and vacuum hoses to detect leaks.
3. Replace any damaged hoses or gaskets as necessary.

5. Reconnect Battery and Test

Reconnect the battery terminals securely.
Start the engine and allow it to idle. Monitor for any irregularities.
