Solution

1. Preparation

Gather 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 shock.

2. Inspect and Replace Spark Plugs

Remove the engine cover if applicable.
Use a socket set to remove spark plug wires or coils.
Remove the spark plugs using a spark plug socket.
Inspect the spark plugs for wear; replace with OEM specifications if necessary.
Reinstall spark plugs and reconnect coils or wires.

3. Check Ignition Coils

With the engine off, visually inspect ignition coils for cracks or damage.
Use a multimeter to test the resistance of each coil; replace any that are out of specification.
Reinstall any coils that are functioning properly.

4. Test Fuel Pressure

Connect a fuel pressure gauge to the fuel rail Schrader valve.
Turn the ignition to the "on" position without starting the engine and check the pressure reading.
If pressure is low, inspect the fuel pump and filter; replace as needed.

5. Examine Air Filter

Locate the air filter housing and open it.
Remove the air filter and inspect for dirt and blockages.
Replace with a new air filter if necessary, ensuring a proper seal upon reinstallation.

6. Inspect Vacuum Hoses

Visually inspect all vacuum hoses for cracks or disconnections.
Replace any damaged hoses with OEM parts.
Reconnect all hoses securely.
