Solution

1. Preparation

Ensure the vehicle is parked on a flat, stable surface.
Disconnect the battery to prevent electrical shorts.
Gather all necessary tools and parts.

2. Inspect and Replace Ignition Components

Sub-steps:
1. Remove the engine cover, if applicable, using a socket set.
2. Disconnect the wiring harness from each ignition coil.
3. Remove the ignition coils using a socket set, taking note of their order.
4. Remove old spark plugs using a spark plug socket; inspect for wear or carbon buildup.
5. Replace spark plugs with new ones (torque to manufacturer specifications, typically around 13-16 lb-ft).
6. Reinstall ignition coils, ensuring they are secured and the wiring harness is connected.

3. Inspect and Repair Exhaust System

Sub-steps:
1. Raise the vehicle securely using jack stands.
2. Inspect the exhaust system from the manifold to the tailpipe. Look for rust, holes, or damaged gaskets.
3. Replace any damaged sections of pipe or gaskets. Use exhaust assembly paste on joints if needed.
4. Ensure all hangers and clamps are tight and secure.

4. Check for Vacuum Leaks

Sub-steps:
1. Use a carburetor cleaner or smoke machine to test for leaks around the intake manifold and vacuum hoses.
2. Replace any damaged hoses or seals found during the inspection.
