Well, before the road trip, I decided to change my fluids/filters. That proved to be a headache on the transmission end of things. Anyways, I drove from CO to MI, roughly 1300mi, at about 65-70mph the whole way. By the end of my trip, the transmission or something? started to slip or it seemed, when slowing down, be at a high idle. For example, driving through a fast food place, it just likes to idle high. I tried messing with my airflow adjustment, nothing. Well, I am wondering what might have happened and what I could do. Thanks much guys!
