Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, fuel pressure gauge, multimeter, and basic hand tools.
Disconnect the battery to ensure safety while working on electrical components.

2. Address Diagnostic Trouble Codes

Use the OBD-II scanner to clear any codes after repairs.
If codes indicate a specific component failure, replace the faulty component (e.g., ignition coil, oxygen sensor).

3. Replace Spark Plugs and Ignition Coils

Remove the ignition coil cover by unscrewing any retaining bolts.
Disconnect the electrical connectors from the ignition coils.
Remove the ignition coils and spark plugs using a socket wrench.
Install new spark plugs to the manufacturer’s torque specifications (typically around 15 ft-lbs).
Reinstall the ignition coils and connect the electrical connectors.

4. Inspect and Replace Air Filter

Locate the air filter housing and unclip or unscrew the cover.
Remove the old air filter and inspect for debris or excessive dirt.
Install a new air filter and secure the housing cover.

5. Check and Repair Vacuum Leaks

Visually inspect all vacuum hoses and connections for signs of wear or damage.
Replace any damaged hoses and ensure all connections are tight.

6. Fuel System Check

Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position (do not start) to check fuel pressure.
Compare the reading to the manufacturer’s specifications (typically around 50-60 psi).
If pressure is low, consider replacing the fuel pump or checking the fuel filter for clogs.
