Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Clean the Throttle Body

Remove the air intake duct connected to the throttle body (use a socket set).
Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.
Reattach the air intake duct and secure it with clamps.

3. Inspect and Clean the Idle Air Control Valve

Locate the idle air control valve (IAC) on the throttle body.
Remove the IAC connector and screws holding it in place (use a screwdriver).
Clean the IAC with an appropriate cleaner and inspect for wear or damage.
Reinstall the IAC and reconnect the electrical connector.

4. Address Fuel System Issues

Using a fuel pressure gauge, connect it to the fuel rail and check for proper fuel pressure (refer to the service manual for specific values).
If pressure is low, replace the fuel pump.
If needed, replace the fuel filter as preventative maintenance.

5. Check and Change Engine Oil

Check the oil level with the dipstick; add oil if low.
If the oil is dirty, change the engine oil and filter using the manufacturer-recommended oil type.
