how to fix my Toyota Tacoma N300 (2016-Present) that stalls when stopping?

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to ensure safety.
• Allow the engine to cool before starting any work.

2. Clean the Throttle Body

• Tools Required: Throttle body cleaner, soft cloth, socket set.
• Remove the air intake duct connected to the throttle body.
• Spray throttle body cleaner inside the throttle body and wipe with a soft cloth.
• Ensure the throttle plate moves freely and is clean.

3. Inspect and Clean the Idle Air Control Valve (IACV)

• Tools Required: Socket set, cleaning solvent.
• Locate the IACV, usually near the throttle body.
• Disconnect the electrical connector and remove the IACV.
• Clean the valve with solvent to remove any carbon deposits.
• Reinstall the IACV and reconnect the electrical connector.

4. Check Fuel Pressure

• Tools Required: Fuel pressure gauge.
• Locate the fuel rail and connect the fuel pressure gauge.
• Start the engine and check the pressure against manufacturer specifications (typically 50-60 PSI).
• If pressure is low, inspect fuel filters and fuel pump for issues.

5. Inspect Engine Air Filter

• Tools Required: None (or a screwdriver for clips).
• Remove the air filter housing cover.
• Inspect the air filter for dirt and blockages.
• Replace the air filter if it is dirty or clogged.
