For maybe 2-3 months I have been experiencing more or less a rough idle. It is a 2000 GS 300. I remember during the summer how smooth as silk it was. Now during idle and also during acceleration, it just feels a little rough. I brought it to the dealer and they said that no codes appeared, so that it was fine. They mentioned the reformulated gasoline that is used during the winter months that could be causing this.

Does anyone have this problem?

 

If its the gasoline, can't you throw in some fuel cleaner gunk crap and flush it all out?

 

Next time you fill up your tank, try using some fuel injector cleaner. It coudn't hurt.
