Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, fuel pressure gauge, multimeter.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Retrieve Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn on the ignition without starting the engine.
Record any active trouble codes for further analysis.

3. Inspect and Replace Spark Plugs

Remove the ignition coil covers (if applicable).
Take out the spark plugs using a socket and ratchet.
Inspect the spark plugs for wear (e.g., carbon buildup, electrode damage).
Replace with new spark plugs according to manufacturer specifications (use proper gap settings).
Reinstall the ignition coils and covers.

4. Check Fuel System

Use a fuel pressure gauge to test the fuel system pressure.
If pressure is low, check the fuel pump and filter for issues.
Replace the fuel filter if clogged and consider replacing the fuel pump if necessary.

5. Inspect Air and Exhaust Systems

Examine the air intake for obstructions or leaks in hoses.
Check the mass air flow (MAF) sensor and clean if necessary.
Inspect the exhaust system for blockages or leaks, particularly around the catalytic converter.

6. Final Checks

Reconnect the battery and erase any stored error codes using the OBD-II scanner.
Start the engine and monitor for any new codes or symptoms.
