My car idles at 1and ahalf to 2 rpms after warm up and driving for about a mile or so. I have replaced fuel filter, 1 oxygen sensor and iac valve service engine light still comes on what could possibly be the problem I believe it may be a sensor but which one

What code does it have? Check for vacuum leaks, sounds like you have one. Use carb cleaner to carefully spray around the top of the engine, when the rpms change you have sprayed a leak. Have you ever tried to adjust the idle stop screw? If so the base idle may be off, the computer is supposed to set idle so if the screw is moved it can cause issues
