Solution

1. Preparation

Gather tools and safety equipment.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Check Engine Oil

Remove the engine oil dipstick and wipe it clean.
Insert the dipstick back into the tube and remove it again to check the oil level.
If low, add the appropriate oil type as specified in the owner's manual.
If oil is dirty or contaminated, proceed to change the oil and filter.

3. Inspect Timing Chain/Belt

Remove the engine cover if applicable (typically involves unscrewing fasteners).
Check for excessive slack in the timing chain or signs of wear on the timing belt.
If worn or loose, replace the timing chain/belt and tensioner as per the manufacturer’s specifications.

4. Tighten Loose Components

Inspect the valve cover for loose bolts and tighten them to the manufacturer’s torque specifications.
Check exhaust manifold bolts and tighten if necessary.

5. Replace Ignition Components

Remove the spark plugs using a socket wrench.
Inspect plugs for wear; replace if necessary.
Check ignition coils for proper function; replace any faulty coils.
