I have a new issue with my truck. No codes or anything. Doesnt run different etc. Just the RPMs take a nose dive sometimes, usually going slow in parking lots. If you give it gas and let off, rpms will dip really low and then pop back up, after feeling like its gonna stall. I dont have a log of it doing it yet, but will post the tune. Maybe its something that needs adjusted now that its warmer out? Has me scratching my head lol
