I went to jump off my truck today and was holding rmp's at 2k and it started jumping to 2400-2600 rpms and dropping back to 2k. It seemed to do it every two seconds or so. I've looked for a vacuum leak and cant find anything, plugs have 20k on them and replaced TPS and crank position sensor 2 years ago.
Off the wall, question. Ive been having a rhythmic vibration at 60+ is there any chance these could be linked? I haven't noticed or felt a rpm surge, before today when jumping the truck.
