Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is cool.
Gather necessary tools and parts.
Disconnect the battery to ensure safety when working on electrical components.

2. Check Engine Oil

Tools Required: Oil wrench, oil catch pan, funnel
Remove the oil dipstick to check the oil level; add oil if low.
If the oil appears dirty or has metal shavings, replace it.
Sub-steps:
- Drain the old oil using an oil catch pan.
- Replace the oil filter using an oil wrench.
- Refill with manufacturer-recommended oil and check levels.

3. Inspect Engine Components

Tools Required: Socket set, torque wrench
Check engine mounts for wear or cracks that could cause vibrations.
Inspect the timing chain/belt for proper tension and wear.
Sub-steps:
- Tighten loose bolts to manufacturer specifications.
- Replace damaged mounts or timing components as needed.

4. Perform Compression Test

Tools Required: Compression tester
Remove spark plugs and insert the compression tester into each cylinder.
Sub-steps:
- Crank the engine several times to get a reading.
- Compare readings to manufacturer specifications; replace components if readings are low.

5. Fuel Injector and Spark Plug Inspection

Tools Required: Multimeter, socket set
Test fuel injectors for proper operation using a multimeter.
Remove and inspect spark plugs for wear or fouling.
Sub-steps:
- Clean or replace spark plugs as necessary.
- Replace faulty fuel injectors based on test results.
