Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, screwdrivers.
Ensure the engine is cool and the vehicle is parked on a level surface.
Disconnect the battery to prevent electrical shorts while working.

2. Inspect and Replace Spark Plugs

Remove Engine Cover (if applicable):
- Use a socket set to remove bolts securing the engine cover.
- Carefully lift off the cover and set it aside.
Remove Spark Plug Wires/Coils:
- Mark and disconnect spark plug wires or ignition coils from each spark plug.
Remove Spark Plugs:
- Use a spark plug socket to carefully unscrew and remove each spark plug.
Inspect Spark Plugs:
- Check for signs of wear, fouling, or damage. Replace any faulty plugs with new ones.
Install New Spark Plugs:
- Torque new spark plugs to the manufacturer’s specifications (usually around 12-15 ft-lbs).
Reconnect Spark Plug Wires/Coils:
- Ensure each wire or coil is connected to the correct plug.

3. Check for Exhaust Leaks

Inspect Exhaust System:
- Look for cracks, holes, or loose connections in the exhaust system.
Tighten Loose Bolts:
- Use a torque wrench to secure any loose bolts on the exhaust manifold and joints.
Replace Damaged Components:
- If leaks are found, replace gaskets or damaged sections of the exhaust pipe.

4. Verify and Test Intake System

Inspect Air Intake and Vacuum Lines:
- Check for cracks or disconnections in the intake manifold and vacuum hoses.
Replace Faulty Components:
- Replace any damaged hoses or gaskets as necessary.
Reassemble Any Removed Components:
- Reconnect any components removed during the inspection.
