Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface, and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Replace Faulty Components (if diagnosed)

A. Spark Plugs

Use a spark plug socket to unscrew the old spark plugs.
Inspect the old plugs for wear; replace with new plugs if necessary (refer to the owner's manual for the correct type).
Torque the new plugs to the manufacturer's specifications (usually around 15-20 lb-ft).

B. Ignition Coils

Disconnect the wiring harness from the ignition coil.
Remove the mounting bolts for the ignition coil.
Replace with new ignition coils, tightening bolts to the specified torque.
Reconnect the wiring harness.

3. Address Vacuum Leaks

Inspect and replace any damaged vacuum hoses.
Use a smoke machine or spray soapy water on hoses while the engine is running to detect leaks.
Tighten or replace any loose clamps or connectors.
