Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery for safety.
Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Inspect and Clean Air Filter

Remove the air filter cover.
Take out the air filter and inspect for dirt and blockages.
If dirty, replace with a new air filter.
Reinstall the air filter and cover securely.

3. Check Fuel Pressure

Connect a fuel pressure gauge to the fuel rail test port.
Turn the ignition to the "ON" position without starting the engine and observe the pressure reading.
Ensure the pressure is within manufacturer specifications (usually around 40-50 psi).
If pressure is low, inspect the fuel pump and fuel filter for issues.

4. Inspect and Replace Spark Plugs

Remove the ignition coil or spark plug wires.
Use a socket wrench to remove the spark plugs.
Inspect the plugs for signs of wear or fouling; replace if necessary.
Torque new spark plugs to the manufacturer’s specifications (usually around 13-15 ft-lbs).

5. Clean Throttle Body

Remove the air intake duct connected to the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding area.
Reassemble the intake duct securely.

6. Reconnect Battery

Reconnect the negative terminal of the battery.
