Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Access Ignition Components

Sub-steps:
1. Disconnect the negative battery terminal to prevent electrical shock.
2. Remove any engine covers that obstruct access to ignition components.
3. Carefully remove the spark plug wires or ignition coils.

3. Inspect and Replace Spark Plugs

Sub-steps:
1. Remove the spark plugs using a spark plug socket and ratchet.
2. Inspect the spark plugs for wear or damage. Replace if necessary.
3. Set the gap on new spark plugs to the manufacturer's specification.
4. Install the new or inspected spark plugs, tightening to the specified torque (usually around 15-20 Nm).

4. Check and Replace Ignition Coils

Sub-steps:
1. Test the ignition coils with a multimeter to check for proper resistance.
2. If faulty, disconnect the electrical connectors and remove the coils.
3. Install new ignition coils, ensuring they are securely seated and connected.

5. Inspect Fuel System

Sub-steps:
1. Connect a fuel pressure gauge to the fuel rail.
2. Turn the ignition to the "ON" position without starting the engine and check the pressure.
3. If pressure is low, inspect the fuel pump and fuel filter for clogs or failures.
4. Replace the fuel filter if necessary and test the fuel pump operation.

6. Reassemble and Test

Sub-steps:
1. Reconnect all components, ensuring all connections are secure.
2. Reconnect the negative battery terminal.
3. Start the engine and observe for smooth operation.
