Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the vehicle battery to ensure safety during repairs.
Allow the engine to cool before starting work.

2. Retrieve Error Codes

Connect the OBD-II scanner to the diagnostic port.
Turn the ignition key to the "On" position without starting the engine.
Record any error codes displayed and address them according to the manufacturer's guidelines.

3. Inspect and Replace Ignition Components

Remove the ignition coil covers using a socket set.
Inspect spark plugs for wear; replace if necessary (use OEM parts).
Reinstall ignition coils, ensuring proper torque specifications (typically around 8-10 Nm).

4. Examine Fuel System

Locate the fuel pump in the fuel tank and check the connections.
If the fuel filter is clogged, replace it according to manufacturer specifications.
Test fuel pressure using a fuel pressure gauge to ensure it meets manufacturer requirements (generally around 40-50 psi for most vehicles).

5. Inspect Air Intake and Exhaust

Remove the air filter housing and inspect the air filter for dirt or blockages; replace if necessary.
Inspect the exhaust system for leaks or blockages, particularly at the catalytic converter.
Clean any debris from the intake manifold and throttle body.

6. Reassemble and Connect Battery

Reassemble any components that were removed during the inspection.
Reconnect the vehicle battery.
Clear any error codes using the OBD-II scanner.
