Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Replace Spark Plugs

Sub-steps:
1. Disconnect the negative battery terminal to prevent electrical shorts.
2. Remove the engine cover if applicable.
3. Using a spark plug socket, remove the old spark plugs.
4. Check the gap on new spark plugs and adjust if necessary.
5. Install new spark plugs and torque to manufacturer specifications (usually around 13-15 lb-ft).

3. Inspect and Replace Ignition Coils

Sub-steps:
1. Disconnect the electrical connector from each ignition coil.
2. Remove the bolts securing the ignition coils and pull them out gently.
3. Inspect coils for cracks or carbon tracking; replace if damaged.
4. Reinstall new ignition coils and reconnect electrical connectors.

4. Check Fuel Delivery

Sub-steps:
1. Connect a fuel pressure gauge to the fuel rail.
2. Turn the ignition to the "On" position without starting the engine to check fuel pressure.
3. Compare the reading to the manufacturer's specifications (typically around 40-50 psi).
4. If pressure is low, inspect the fuel pump and fuel filter for issues.

5. Inspect Air Intake System

Sub-steps:
1. Visually inspect the air filter and replace if dirty.
2. Check for any signs of vacuum leaks in hoses connected to the intake manifold.
3. Clean the throttle body using throttle body cleaner.
