Weird high idle

Ok so i was driving back home tonight and noticed that my truck had itself idled up to 1000rpm even though the truck was at op temp. It was 39 degrees out so a little chilly but nothing too serious. I recently installed an edge drag comp and the truck would run the same idle speed with the chip on and off. Bumping the throttle also did nothing to brig it down either. I had a smarty on the truck before this and last winter it would high idle but it would idle faster and i could just bump the throttle to make it go down. Im kinda confused any of yall got suggestions?

My truck did this pulling a big enclosed trailer to Houston probably about 5-6 years back. Only did it that one trip though. After that never has it happened again.
