Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, fuel pressure gauge, multimeter, and basic hand tools.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Engine Mount Inspection

Sub-steps:
1. Locate the engine mounts (typically found at the front, rear, and sides of the engine).
2. Visually inspect the mounts for cracks, tears, or excessive wear.
3. Use a pry bar to test the mounts for excessive movement.
4. If damaged, remove the bolts securing the mount and replace with new mounts, ensuring proper torque specifications are followed (usually around 40-55 ft-lbs for most mounts).

3. Vacuum Leak Repair

Sub-steps:
1. Inspect hoses connected to the intake manifold for cracks or disconnections.
2. If a leak is found, replace the damaged hose or reattach it securely.
3. If no visible leaks are found, perform a smoke test to identify hidden leaks.
4. Repair any leaks found by replacing gaskets or hoses as necessary.

4. Fuel System Check

Sub-steps:
1. Connect the fuel pressure gauge to the fuel rail test port.
2. Turn the ignition to the "ON" position (do not start) to check pressure readings against manufacturer specifications (typically 30-45 psi for RAV4).
3. If pressure is low, inspect the fuel pump and filter for clogs or malfunctions.
4. Replace the fuel pump or filter if needed.

5. Ignition System Inspection

Sub-steps:
1. Remove the spark plugs and inspect for wear, deposits, or damage.
2. Check the gap of the spark plugs with a feeler gauge and adjust or replace if out of specification (typically 0.043 inches).
3. Inspect ignition coils for cracks or signs of arcing, and replace as necessary.
