Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, fuel pressure gauge.
Safety Warnings: Disconnect the battery before starting work on electrical systems.

2. Address Exhaust Issues

Step 1: Raise the vehicle safely using jack stands.
Step 2: Inspect the exhaust system visually for any holes or rusted areas.
Step 3: If leaks are found, mark the areas for repair or replacement.
Step 4: For minor holes, use exhaust patching material and clamps, or replace damaged sections as required.

3. Replace Spark Plugs (if necessary)

Step 1: Remove the engine cover (if applicable) using a socket set.
Step 2: Disconnect the ignition coils from the spark plugs.
Step 3: Use a spark plug socket to remove the old spark plugs.
Step 4: Install the new spark plugs, hand-tighten, and then torque to manufacturer specifications (typically around 15-20 lb-ft).
Step 5: Reconnect the ignition coils and replace the engine cover.

4. Repair or Replace Intake System Components

Step 1: Inspect the intake manifold and hoses for damage or disconnections.
Step 2: Replace any damaged hoses or gaskets as needed.
