Solution

1. Preparation

Gather tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Clean the Throttle Body

Tools Required: Throttle body cleaner, soft brush
Remove the intake duct connected to the throttle body.
Spray throttle body cleaner into the throttle body and use a soft brush to remove carbon deposits.
Open the throttle plate with your hand (if safe to do so) to clean behind it.
Allow the cleaner to dry before reassembling.

3. Replace the Idle Air Control Valve (if faulty)

Tools Required: Socket set, torque wrench
Disconnect the electrical connector from the IACV.
Remove the mounting bolts and take out the old IACV.
Install the new IACV, ensuring it is seated properly.
Torque the screws to the manufacturer’s specifications.
Reconnect the electrical connector.

4. Check and Repair Vacuum Leaks

Tools Required: Smoke machine or carburetor cleaner
Use a smoke machine to introduce smoke into the intake system and look for smoke escaping from any vacuum lines.
Alternatively, spray carburetor cleaner around the vacuum lines while the engine is running; if the idle changes, a leak is present.
Replace any damaged or cracked vacuum hoses.

5. Check the Fuel System

Tools Required: Fuel pressure gauge
Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "On" position (do not start) and check the fuel pressure reading against manufacturer specifications.
If pressure is low, investigate fuel pump operation or replace the fuel filter if clogged.
