Solution

1. Preparation

Gather necessary 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 and Record Codes

Use an OBD-II scanner to retrieve and document any trouble codes.
Note any freeze frame data associated with the codes for further analysis.

3. Inspect Ignition Components

Remove the engine cover if applicable.
Disconnect the ignition coil connectors.
Remove the spark plugs using a socket wrench.
Inspect spark plugs for fouling or wear; replace if necessary.
Test ignition coils with a multimeter; replace any that are out of specification.

4. Check Fuel System

Connect a fuel pressure gauge to the fuel rail.
Start the engine and record the fuel pressure.
Compare readings to manufacturer specifications; replace fuel pump or filter if pressure is low.

5. Inspect Air Intake and Exhaust

Visually inspect the air filter for clogs; replace if dirty.
Check for vacuum leaks in hoses connected to the intake manifold.
Inspect the exhaust system for blockages or damage, such as a clogged catalytic converter.

6. Reconnect Battery and Clear Codes

Reconnect the battery terminals securely.
Use the OBD-II scanner to clear any trouble codes.
Start the engine and observe if the check engine light remains off.
