Thansk you all for now,

Recently, engine speed fluctuation occurs when the engine is hot. Meanwhile, the car is shaking.

- There is no problem going on the road.
- When I press the gas, the cycle rises. There is no problem in that either.

Its no problem when motor is cold.

My vehicle, 1.4i 8v bva 2003,

Sounds like it might be a vacuum leak.
Listen for "hissing" in the engine bay.
Get a can of Starting Fluid and spray it around the inlet manifold.
Look on Youtube "finding vacuum leaks in your engine".

DANGER, WARNING! Starting fluid is highly flammable! Do not spray it near the exhaust system. Read the directions on the can!!
