why is my Toyota Tacoma N300 (2016-Present) shaking at a stoplight

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to prevent electrical shorts.
• Allow the engine to cool before starting work.

2. Inspect and Replace Engine Mounts (if necessary)

• Tools Required: Socket set, torque wrench, pry bar
• Instructions:
  1. Raise the vehicle safely on jack stands and remove the front wheels for better access (if necessary).
  2. Locate the engine mounts; typically found connecting the engine to the chassis.
  3. Use a pry bar to carefully lift the engine slightly to relieve pressure on the mounts.
  4. Remove the bolts securing the old mounts using a socket set.
  5. Install new engine mounts and torque the bolts to manufacturer's specifications (typically 40-50 ft-lbs, check service manual).
  6. Reconnect the negative battery terminal.

3. Clean or Replace Spark Plugs and Ignition Components

• Tools Required: Spark plug socket, torque wrench, dielectric grease
• Instructions:
  1. Remove the ignition coils or spark plug wires as applicable.
  2. Remove the old spark plugs using the spark plug socket.
  3. Inspect the spark plugs for wear, and replace them if they appear damaged or worn.
  4. Apply dielectric grease to the new spark plugs and install them, torquing to manufacturer specifications (typically around 13 ft-lbs).
  5. Reinstall ignition coils or spark plug wires.

4. Inspect and Replace Idle Air Control Valve (if needed)

• Tools Required: Socket set, cleaning solvent (if cleaning), replacement IAC valve
• Instructions:
  1. Locate the idle air control valve, usually attached to the throttle body.
  2. Disconnect the electrical connector and remove the mounting screws.
  3. Clean the IAC valve with solvent if it appears dirty; otherwise, replace it with a new one.
  4. Reinstall and reconnect the IAC valve.
