Solution

1. Preparation

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

2. Inspect and Clean Throttle Body

Remove the air intake duct for access.
Use a throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
Reattach the air intake duct securely.

3. Check and Replace Idle Air Control Valve (if faulty)

Locate the idle air control valve on the throttle body.
Disconnect the electrical connector and remove the mounting screws.
Install the new IAC valve in reverse order of removal and reconnect the electrical connector.

4. Inspect and Replace Spark Plugs and Ignition Coils (if necessary)

Remove the ignition coils from the spark plug wells.
Extract the spark plugs using a spark plug socket and ratchet.
Inspect for wear and carbon buildup; replace with manufacturer-recommended plugs.
Reinstall the ignition coils after replacing the spark plugs.

5. Verify Fuel System Integrity

Check the fuel pump operation by listening for it when the ignition is turned on.
Inspect the fuel filter and replace if clogged or overdue.
If necessary, check the fuel pressure using a fuel pressure gauge to ensure it meets specifications.
