on a cold start up it revs to 2k, after being warmed up it drops down to 1.5k. Before this happened the rpm was fluctuating 800-1.5k, and i never got around to fix but now it stays at a steady 1.5k. Not sure if its the iacv or pcv valve because it is not fluctuating anymore. Any ideas of what it could be would help.


heres a video of it, staying at a steady 1.5k up until i rev it. Drops back down to normal and goes up to 2k then to 1.5k

This exact issue was happening to me last week. I replaced the IACV but that didn't fix the problem. So I took out the FITV, took it apart, cleaned it, and put it back together, screwing the valve in tighter (it had come loose). That fixed the idle. There is a step-by-step floating around HT...
