Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to ensure safety during repairs.
Allow the engine to cool down if it was recently running.

2. Clean or Replace the Throttle Body

Tools Required: Socket set, throttle body cleaner, soft cloth.
Remove the intake hose connected to the throttle body.
Use throttle body cleaner to clean the inside of the throttle body.
Wipe it down with a soft cloth to remove any carbon deposits.
Reattach the intake hose securely.

3. Inspect and Clean the Idle Air Control Valve (IACV)

Tools Required: Socket set, screwdriver, cleaning solvent.
Locate the IACV, usually near the throttle body.
Disconnect the electrical connector and remove the IACV from its mount.
Clean the valve using a suitable cleaning solvent and a soft brush.
Reinstall the IACV and reconnect the electrical connector.

4. Test Fuel Pressure

Tools Required: Fuel pressure gauge.
Locate the fuel rail and connect the fuel pressure gauge.
Turn the ignition to the "ON" position without starting the engine and check the pressure reading.
If the pressure is below specifications, inspect the fuel pump and filter for issues.
Replace the fuel pump or filter if necessary.

5. Recheck Engine Oil

Ensure the oil level is within the recommended range and the oil is clean.
If the oil is low or dirty, change the engine oil and filter.
