Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical issues.

2. Scan and Identify Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Record any trouble codes and their descriptions.
Use the codes to guide further inspection and repairs.

3. Inspect and Replace Components

A. Air Filter Inspection

Locate the air filter housing.
Remove the air filter and inspect for dirt and blockages.
Replace the air filter if it is dirty or damaged.

B. Spark Plug Inspection

Remove the ignition coil cover (if applicable).
Take out the spark plugs using a socket wrench.
Inspect the spark plugs for wear, cracks, or carbon buildup.
Replace any faulty spark plugs with manufacturer-recommended parts.

4. Check and Repair Vacuum Leaks

Visually inspect all vacuum hoses for cracks or disconnections.
Use a smoke machine or carburetor cleaner to detect leaks.
Replace or repair any damaged hoses.

5. Fuel System Check

Verify fuel pressure using a fuel pressure gauge.
If pressure is low, inspect the fuel pump and filter for blockages.
Replace the fuel filter if necessary.

6. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and allow it to reach normal operating temperature.
Monitor for any persistent check engine light or rough idle.
