Solution

1. Preparation

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

2. Inspect Engine Mounts

Tools Required: Socket set, torque wrench
Remove the fasteners securing the engine mounts to the engine and frame.
Inspect the rubber isolators for cracks or deterioration.
If damaged, replace the engine mounts with OEM or high-quality aftermarket parts.
Torque the fasteners to the manufacturer specifications.

3. Replace Spark Plugs

Tools Required: Spark plug socket, ratchet, torque wrench
Remove the ignition coils by unscrewing them from the valve cover.
Take out the old spark plugs using the spark plug socket.
Install new spark plugs, ensuring they are gapped correctly according to manufacturer specifications.
Reinstall the ignition coils and secure them with the appropriate torque.

4. Clean Throttle Body

Tools Required: Throttle body cleaner, lint-free cloth
Remove the air intake hose to access the throttle body.
Spray throttle body cleaner onto the throttle plate and wipe with a lint-free cloth until clean.
Reattach the air intake hose ensuring all clamps are secured.

5. Test Fuel Pressure

Tools Required: Fuel pressure gauge
Locate the fuel pressure test port on the fuel rail.
Connect the fuel pressure gauge and turn the ignition to the "ON" position without starting the engine.
Check the pressure reading against manufacturer specifications. Replace the fuel pump if the pressure is low.
