My trims are all over the place at idle and during acceleration and stopping/slowing down. They nearly always go to zero once a steady speed is attained and maintained for a few minutes at least. And right after refueling it's not uncommon for them to shoot up to -25% but the CEL does not alight as it is figuring out the new alcohol content. Different fuels, different fluctuations in the trims.
