Solution

1. Preparation

Gather all tools and parts needed for the repair.
Disconnect the negative battery terminal to prevent electrical shock.

2. Inspect and Replace Spark Plugs

Tools Required: Socket set, torque wrench, spark plug socket.
Remove spark plug wires or ignition coils (if applicable).
Use a spark plug socket to remove each spark plug.
Inspect plugs for wear and replace if necessary.
Install new spark plugs to the manufacturer's torque specification (typically around 13-15 ft-lbs).

3. Check and Replace Ignition Coils

Tools Required: Socket set, multimeter.
Remove the ignition coil assembly from the engine.
Use a multimeter to test the resistance of each coil; compare to specifications in the service manual.
Replace any faulty ignition coils with new ones.
Reinstall the ignition coils and ensure they are seated properly.

4. Inspect and Repair Exhaust System

Tools Required: Wrench set, exhaust pipe cutter (if necessary), exhaust sealant.
Visually inspect the exhaust manifold and pipes for any cracks or holes.
If leaks are found, either replace the affected section or use exhaust sealant as a temporary fix.
Reassemble any components removed during inspection.
