Solution

1. Preparation

Gather tools and parts needed.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, torque wrench, pry bar
Instructions:
- Locate the engine mounts (usually found at the front, rear, and sides of the engine).
- Use the socket set to remove the bolts securing the engine mount to the engine and chassis.
- Use a pry bar to gently lift the engine if necessary to remove the old mount.
- Install the new engine mount by reversing the removal steps, ensuring bolts are torqued to manufacturer specifications.

3. Check and Replace Spark Plugs

Tools Required: Ratchet and socket set, spark plug gap tool
Instructions:
- Remove the ignition coils or cover to access the spark plugs.
- Unscrew and remove the old spark plugs.
- Check the gap on new spark plugs using the gap tool and adjust as necessary.
- Install new spark plugs and reconnect ignition coils or cover.

4. Clean or Replace the Idle Air Control Valve (IAC)

Tools Required: Screwdriver set, cleaning solution (if applicable)
Instructions:
- Locate the IAC valve, usually found on the throttle body.
- Disconnect the electrical connector and remove any screws or bolts securing the valve.
- If cleaning, use the cleaning solution to remove carbon deposits. If replacing, install the new IAC valve in reverse order, ensuring a secure fit.
