There are usually several situations to diagnose engine idle jitter. The most common cause of automobile jitter is the serious carbon deposition in the engine. There is a general cleaning agent inside the engine, which can remove carbon deposit and clean carbon deposit sludge without disassembling the engine oil. It is very convenient to use, and the suspension will not block together and will not be mixed with engine oil to cause stratification, so that your engine can be cleaned better and safer.
