I would have made their dumbasses drain the tank. I would never run a full tank of 87 through that engine right off the lot. And they need to be punished for stupidity.
As for the idle, hehehe, yeah. it is supposed to be like that.
Also bear in mind that idle is basically the bear minimum the engine needs to do to...stay running. So you will notice when it's cold the computer idles it higher, and when it warms up it idles lower. That isn't going to be the smoothest way to operate the engine, no, but...it's fine.
