Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cold and the vehicle is parked on a level surface.
Disconnect the battery to prevent electrical shorts.

2. Check Engine Oil

Remove the dipstick and wipe it clean.
Reinsert the dipstick and remove it again to check the oil level; add oil if it’s low.
If the oil is dirty or contaminated, perform an oil change.

3. Inspect Valve Clearance

Remove the valve cover using a socket set.
Use a feeler gauge to measure the clearance between the rocker arms and the valve stems.
Adjust the clearance according to the manufacturer’s specifications if it’s out of range.

4. Inspect Timing Belt

Remove any covers obstructing access to the timing belt.
Visually inspect the timing belt for cracks, fraying, or excessive wear.
If any damage is found, replace the timing belt following manufacturer specifications for tension and alignment.

5. Fuel Injector Check

Remove the fuel rail assembly to access the injectors.
Inspect each injector for clogs or leaks.
Clean or replace any faulty injectors as necessary.
