Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the negative battery terminal to prevent electrical shorts.
Allow the engine to cool down before beginning work.

2. Addressing Trouble Codes

Use the OBD-II scanner to clear the error codes after repairs are completed.
If the code is related to emissions, inspect and replace the faulty components (e.g., O2 sensors or catalytic converter).

3. Replacing Spark Plugs

Remove the engine cover if necessary to access the spark plugs.
Use a socket wrench to remove the old spark plugs.
Gap the new spark plugs as per manufacturer specifications.
Install the new spark plugs and torque them to the recommended specifications (usually around 13 lb-ft for most applications).

4. Repairing Vacuum Leaks

Inspect all vacuum hoses for cracks or disconnections.
Replace any damaged hoses.
Use a smoke machine to test for leaks if necessary.

5. Fuel Pressure Test and Repair

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the "On" position to check fuel pressure; it should match manufacturer specifications.
Replace the fuel pump or filter if pressure is below specifications.
