Well, it can't be doing that at the same time. It's that your long-term and short-term I changing. Because when you're idling it can do one thing. Then when you go mid speed it can be different and high speed can be different. So if you watch the short-term fuel trim as you drive, you're probably see it changes while you're driving. The long term field trim basically tells you the average of it all, which is the bigger problem whatever the long term says
