Solution

1. Preparation

Gather tools and ensure the vehicle is on a flat surface.
Disconnect the negative terminal of the battery for safety.
Tools required: OBD-II scanner, socket set, torque wrench, multimeter, vacuum gauge.

2. Inspect Engine Mounts

Remove any covers obstructing access to engine mounts.
Visually inspect each engine mount for cracks, tears, or excessive wear.
Use a pry bar to check for movement; if any mount can be easily moved, it should be replaced.
Replace any faulty engine mounts, ensuring they are torqued to manufacturer specifications.

3. Check Spark Plugs and Ignition Coils

Remove spark plug wires or ignition coil connectors.
Use a socket to remove spark plugs and inspect them for fouling or wear.
Replace any worn or damaged spark plugs with OEM or recommended replacements.
Test ignition coils with a multimeter; replace any that are out of specification.

4. Clean Throttle Body and Idle Air Control Valve

Remove the air intake hose leading to the throttle body.
Use throttle body cleaner and a soft brush to clean the throttle plate and surrounding areas.
Remove the idle air control valve (IAC) and clean it thoroughly with cleaner.
Reinstall the IAC and throttle body carefully, ensuring all connections are secure.

5. Test Fuel Pressure

Connect a fuel pressure gauge to the fuel rail.
Turn the ignition to the "On" position (without starting the engine) to check for initial pressure.
Start the engine and observe if the pressure holds steady according to manufacturer specifications. If pressure is low, consider replacing the fuel filter or checking the fuel pump.

6. Inspect Vacuum Lines

Visually inspect all vacuum lines for cracks, breaks, or disconnections.
Use a vacuum gauge to check for proper vacuum at the intake manifold.
Replace any damaged vacuum lines and ensure all connections are tight.
