Throttle body and air chamber openings were too small. It took me half an hour to heat up and jiggle, and I ended up putting a piece of cloth inside to pull over the throttle body. Once it turned on I had the same issue with noise and a blocked orifice closest to the throttle body. My car was squeaking, I thought it was the gearbox. So I had to take it off again, clean the connector with a screwdriver and knife, and twist it again! Thanks to another reviewer for the help!
