Excelle idle jitter cleaning throttle and idle motor, replacing steam filter are useless.

Excelle idle jitter cleaning throttle and idle motor, replacing steam filter are useless. High power means high compression ratio, which is obviously not the same as jitter. If the fuel does not match the engine, it will naturally burn badly. Especially in the field of ethanol fuel, ethanol fuel seems to be insufficient for engines with large compression ratio. Especially after a long period of high-speed operation. The easiest way is to clean the oil circuit and return to the state of the new car. That's why the new car doesn't shake. The oil tank of this cleaner Sioupu started normally, and it was cleaned after a tank of oil, so it was smooth. It really has nothing to do with the engine.
