Solution

1. Preparation

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

2. Scan for Codes

Use an OBD-II scanner to retrieve diagnostic trouble codes (DTCs).
Note the codes for reference during repairs.

3. Inspect Ignition System

Remove the engine cover (if applicable) using a socket set.
Inspect spark plugs for wear; replace if there are signs of fouling or damage.
Test ignition coils with a multimeter; replace any faulty coils.

4. Check Fuel System

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the "ON" position (do not start the engine) and check fuel pressure.
If the pressure is below specifications, inspect the fuel pump and filter. Replace if necessary.

5. Examine Air Intake and Exhaust Systems

Remove the air filter and inspect for blockages; replace if dirty.
Visually inspect the intake manifold for leaks; use a smoke test if necessary.
Check the exhaust for any obstructions or damage; clear any blockages found.

6. Reassemble and Reconnect Battery

Reinstall any removed components in reverse order.
Reconnect the battery terminals and ensure they're secure.
