Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, multimeter.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety during repairs.

2. Address Engine Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Note any error codes and research their meanings.
Clear the codes and perform a test drive to see if they return.

3. Inspect and Replace Spark Plugs

Remove the ignition coil cover (if applicable).
Unscrew and remove old spark plugs using a socket wrench.
Inspect the old spark plugs for wear; replace with new ones if necessary.
Torque new spark plugs to the manufacturer's specifications (typically around 12-15 lb-ft).

4. Check and Replace Engine Mounts (if necessary)

Support the engine with a jack.
Remove the bolts securing the engine mount to the engine and chassis.
Replace worn or damaged mounts with new ones.
Torque the bolts to manufacturer specifications.

5. Inspect for Vacuum Leaks

Start the engine and use a smoke machine or carburetor cleaner to identify leaks.
Repair any found leaks using appropriate sealants or replace damaged hoses.

6. Verify Fuel Pressure

Connect a fuel pressure gauge to the fuel rail.
Start the engine and observe the pressure readings, ensuring they meet manufacturer specifications.
Replace the fuel pump or filter if pressures are below specifications.
