Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, fuel pressure gauge, and basic hand tools.
Ensure the vehicle is parked on a level surface, and the engine is turned off.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Ignition Components

Sub-step 1: Remove engine cover if necessary to access ignition coils and spark plugs.
Sub-step 2: Use a socket wrench to remove spark plugs; inspect for wear or damage.
Sub-step 3: Test ignition coils with a multimeter for proper resistance; replace any faulty coils.
Sub-step 4: Install new spark plugs, ensuring to torque them to manufacturer's specifications (typically around 15-20 Nm).

3. Examine Fuel System

Sub-step 1: Connect a fuel pressure gauge to the fuel rail; start the engine and check for adequate fuel pressure (usually 3-4 bar).
Sub-step 2: If pressure is low, inspect the fuel pump and fuel filter for blockages or failures.
Sub-step 3: Replace the fuel filter if necessary, and consider replacing the fuel pump if it is not functioning correctly.

4. Check Air and Exhaust Systems

Sub-step 1: Inspect the air intake duct for blockages or cracks; clean or replace as needed.
Sub-step 2: Check the exhaust system for leaks or restrictions that may affect engine performance.
Sub-step 3: Ensure the catalytic converter is functioning properly, and replace if necessary.
