Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and the engine is cool.
Disconnect the battery to ensure safety while working on electrical components.

2. Resolve Ignition Issues

Tools Required: Socket set, spark plug socket, torque wrench
Remove the ignition coil(s) for the affected cylinder(s) as indicated by the error codes.
Inspect and replace worn spark plugs if necessary; use the specified gap settings.
Reinstall the ignition coils securely and torque them to the manufacturer’s specifications.

3. Address Fuel System Problems

Tools Required: Fuel pressure gauge, basic hand tools
Disconnect the fuel line from the fuel rail and attach the fuel pressure gauge.
Turn the ignition to the "ON" position (do not start) to check fuel pressure; compare with manufacturer specifications.
Replace the fuel filter if pressure is below specifications or if it shows signs of clogging.
Reconnect the fuel line and ensure there are no leaks.

4. Repair Vacuum Leaks

Tools Required: Hose clamp pliers, inspection light
Inspect all vacuum hoses and connections for cracks or disconnections.
Replace any damaged hoses or reattach loose connections.
Use a smoke test if necessary to identify hard-to-find leaks.

5. Final Assembly and Testing

Reconnect the battery.
Clear any trouble codes using the OBD-II scanner.
Start the engine and observe for any unusual noises or vibrations.
Test drive the vehicle to ensure the shaking has been resolved.
