Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery before starting any electrical work.

2. Inspect and Replace Spark Plugs

Remove the engine cover using a socket set.
Disconnect the ignition coils by unplugging the electrical connectors.
Unscrew and remove the spark plugs using a spark plug socket.
Inspect the old spark plugs for wear; replace with new plugs if necessary (use OEM equivalent).
Reinstall the spark plugs, ensuring they are properly torqued to the manufacturer’s specifications (typically around 15-20 lb-ft).
Reconnect the ignition coils and secure them in place.

3. Clean Throttle Body

Locate the throttle body and disconnect the air intake hose.
Use throttle body cleaner and a soft cloth to clean the throttle plate and inside of the throttle body.
Ensure no debris falls into the intake manifold.
Reattach the air intake hose securely.

4. Check and Repair Vacuum Leaks

Inspect all vacuum hoses visually for damage or disconnections.
Replace any damaged hoses with new ones of the same diameter and length.
Use a smoke machine or carburetor cleaner to check for leaks around the intake manifold and other connections.

5. Fuel System Inspection

Connect a fuel pressure gauge to the fuel rail test port.
Turn the ignition to the "On" position without starting the engine to check fuel pressure.
Compare the reading to the manufacturer's specifications (usually around 35-50 psi).
If pressure is low, consider replacing the fuel filter and checking the fuel pump.
