Solution

1. Preparation

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

2. Inspect and Replace Engine Mounts

Tools Required: Socket set, torque wrench, pry bar
Remove the bolts securing the engine mounts using a socket wrench.
Carefully lift the engine slightly with a jack and a wood block to relieve stress on the mounts.
Remove the old mounts and replace them with new ones.
Torque the new mounts to the manufacturer’s specifications.

3. Clean or Replace Spark Plugs and Ignition Coils

Tools Required: Socket set, spark plug socket, torque wrench
Remove the ignition coils by unscrewing the securing bolts, then gently pulling them out.
Inspect the spark plugs; if they show signs of wear, replace them with new ones.
Reinstall the ignition coils, ensuring they are seated properly and torqued to specifications.

4. Address Vacuum Leaks

Tools Required: Smoke machine or carburetor cleaner, hose pliers
Use a smoke machine to detect leaks in the intake system. Alternatively, spray carburetor cleaner around the intake manifold while the engine is running; a change in idle indicates a leak.
Repair or replace any damaged hoses or gaskets found during the inspection.

5. Clean the Idle Air Control Valve

Tools Required: Screwdriver set, cleaning solvent
Locate the IAC valve; it is typically near the throttle body.
Remove the IAC valve, clean it thoroughly with a suitable solvent, and reinstall it.
