Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Spark Plugs

Remove the engine cover if necessary to access the spark plugs.
Use a socket wrench to carefully remove the spark plugs.
Inspect the spark plugs for wear, carbon buildup, or damage.
Replace any faulty spark plugs with OEM or recommended parts.
Torque the new spark plugs to the manufacturer’s specifications (typically around 15-25 Nm).

3. Check and Replace Ignition Coils

Disconnect the electrical connectors from the ignition coils.
Remove the bolts securing the ignition coils and gently pull them out of the cylinder head.
Inspect the ignition coils for cracks or signs of wear.
Replace any faulty ignition coils with high-quality replacements.
Reinstall the ignition coils and reconnect the electrical connectors.

4. Inspect the Intake and Exhaust Systems

Visually inspect the intake manifold and air intake hoses for any signs of leaks or damage.
Tighten any loose clamps or connections within the intake system.
Check the exhaust manifold for cracks, leaks, or loose bolts.
If any issues are found, repair or replace the affected components.
