Solution

1. Preparation

Gather tools and parts needed.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Spark Plugs

Remove the ignition coil or spark plug wires.
Use a spark plug socket to remove the old spark plugs.
Inspect the spark plug condition; replace if fouled or worn.
Install new spark plugs, ensuring correct gap specifications (usually 0.030-0.040 inches).
Reattach the ignition coil or spark plug wires.

3. Repair Exhaust Leaks

Visually inspect the exhaust system, focusing on the manifold, gaskets, and connections.
If leaks are found, use penetrating oil to loosen bolts.
Replace any damaged gaskets or components, and reassemble the exhaust system.
Tighten all connections to the manufacturer’s torque specifications.

4. Check and Clean Air Intake System

Disconnect the air intake duct and inspect for blockages or dirt.
Clean the air filter or replace it if necessary.
Reattach the air intake duct securely.

5. Verify Fuel System Functionality

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position without starting the engine to check for proper pressure.
If pressure is low, consider replacing the fuel pump or filter.
