hey id appreciate it if someone would give me an idea of what would make my 96 integra idol so strangely. when i just start the car it runs fine and there seems to be no real significate difference in performance but after it warms up it revs between 1000-2500 rpms on its own while im in nuetral. its just a real pain for obvious noise reasons. if anyone could give me an idea and a price range id appreciate it.
