Hello, honestly, I cannot think of a reason that the engine speed would go up randomly; it is possible that engine speed is being affected by cooling fan turning on and off, air conditioning compressor turning on and off, things of that nature. Hands on testing is needed to see if there's some kind of other problem. https://repairpal.com/auto-repair-near-me
