That would be your MAF sensor. Mass Air Flow. Remove it and ONLY clean it with MAF cleaner in a spray can ( I use CRC brand ). NO rags or toothbrushes, it's a very sensitive instrument. Next after that will be the throttle body itself. It needs to be unplugged and unbolted so you can clean it in a bench. Rags and toothbrushes are allowed if not encouraged. Use Throttle Body Cleaner in a spray can ( CRC ) and keep working at the gunk in there. Mine look like burnt maple syrup. Spray/scrub/spray/scrub. Also do some more research because on some TB's you can't rotate the throttle plate because it's drive by wire, unless you disconnect something else ? Not sure how.
