Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shorts.
Ensure the vehicle is on a flat, stable surface and secure it with wheel chocks.

2. Check and Clean the IAC

Tools Required: Socket set, cleaning spray (throttle body cleaner), soft brush.
Remove the IAC valve from the intake manifold.
Inspect the valve for carbon buildup.
Clean the valve and its seating surface with throttle body cleaner and a soft brush.
Reinstall the IAC valve securely.

3. Replace Faulty Components

Tools Required: Socket set, torque wrench.
If the TPS or IAC is found faulty in diagnostics, replace them:
- Disconnect electrical connectors.
- Remove mounting bolts and take out the faulty component.
- Install the new component and torque bolts to manufacturer specifications.
- Reconnect electrical connectors.

4. Adjust Fuel System

Tools Required: Fuel pressure gauge, wrench set.
Check fuel pressure against manufacturer specifications; if low:
- Consider replacing the fuel pump if it is below the required pressure.
- Inspect and replace fuel filters if clogged.

5. Reassemble and Reconnect

Reconnect the battery.
Ensure all components are properly secured and connected.
