Le Chi 0.8 driving 50000 kilometers, the idle speed is unstable, the car body is shaking, the exhaust gas is not good, and the 1500 neutral can't come down, which makes a lot of noise. Seek liberation. thank you Idle speed instability is usually checked: whether the electronic control system, oil circuit, ignition and gas circuit are normal.

According to what you said, the poor exhaust gas should be caused by oil or gas path (pay special attention to the inspection of "carbon canister" in EVAP of fuel tank evaporation control system), which is caused by insufficient fuel combustion! Check the fault code with the decoder, then clear the fault code and try again. If not, use the oil pressure gauge to check whether the oil pressure is normal and the ignition voltage of the three cylinders is normal at idle speed and high load! If not, go to a regular overhaul factory for maintenance.

That's all I can do. I hope I can help you.
