Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Spark Plug Inspection

Remove the ignition coils using a socket set.
Carefully remove the spark plugs with a spark plug socket and inspect for fouling or damage.
Replace any damaged spark plugs with new ones, ensuring they are gapped according to manufacturer specifications.

3. Ignition Coil Replacement

If any ignition coils show signs of failure, remove them from the engine.
Install new ignition coils, ensuring they are seated properly.
Reconnect the electrical connectors securely.

4. Fuel System Check

Inspect fuel injectors for clogs or leaks; clean or replace them as necessary.
Verify fuel pump operation by checking fuel pressure with a fuel pressure gauge.
Replace the fuel filter if it shows signs of blockage.

5. Vacuum Leak Inspection

Inspect all vacuum hoses for cracks or disconnections; replace any damaged hoses.
Use a smoke machine or carb cleaner to identify leaks around the intake manifold.

6. Engine Compression Test

Remove all spark plugs and attach a compression tester to each cylinder.
Crank the engine and record compression readings; compare against specifications.
Address any cylinders with low compression by checking for valve issues or head gasket leaks.
