What happened to the sudden high idle speed when Buick Excelle was driving?

It may be the deterioration of engine oil or grease deposition caused by untimely maintenance, or the poor throttle and oil circuit, which will seriously damage some parts.

Inferior oil products are also one of the root causes of the above failures. Due to the uneven oil conditions in China, if engine oil is added, it will easily lead to incomplete combustion of the mixture in the engine cylinder, resulting in carbon deposition, which will affect the tightness of the intake valve and exhaust valve, and then reduce the compression ratio. As a result, the vehicle power will also decrease and the idle speed will be unstable.
