Solution

1. Preparation

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

2. Address Fuel System Issues

Sub-steps:
1. Use a fuel pressure gauge to check the fuel pressure. It should be within the manufacturer’s specifications (typically around 40-50 psi).
2. If the pressure is low, inspect and replace the fuel pump if necessary.
3. Replace the fuel filter if it is clogged.

3. Clean the Throttle Body

Sub-steps:
1. Remove the intake duct to access the throttle body.
2. Use throttle body cleaner and a soft cloth to clean the inside of the throttle body, removing any carbon buildup.
3. Reinstall the intake duct and securely fasten all clamps.

4. Inspect and Replace Spark Plugs

Sub-steps:
1. Remove the ignition coil covers and disconnect the ignition coils.
2. Remove the spark plugs using a spark plug socket.
3. Inspect the plugs for wear or carbon buildup; replace them if necessary with OEM specifications.
4. Reinstall the ignition coils and covers, ensuring they are properly seated.

5. Test and Replace the Idle Air Control Valve (IAC)

Sub-steps:
1. Locate the IAC valve and disconnect the electrical connector.
2. Remove the IAC valve from its mounting position.
3. Clean the valve with electrical cleaner and inspect for functionality.
4. If faulty, replace with a new unit and reinstall.
