High RPM After Cleaning Throttle Body
So I cleaned my throttle body today and after reinstalling my car idles at about 2k. I have no idea what's going on, I don't think I have a vacuum leak or anything. Any suggestions?

I don't think it's getting stuck open, it seemed to move smoothly when I was cleaning it. I used WD-40 to clean it, and I drove it for about 15 minutes after I cleaned it and it still has the same problem. So I would think that any leftover WD-40 would be gone.
As for vacuum leaks, what could I have unhooked besides the one hose that is connected to the big plastic intake thing.

did your engine light come on? look for a system too lean error, this usually means you are getting air in the system after the MAF

I checked the throttle body gasket twice to make sure that the unit was sealing against the manifold and it seemed to be fine.
Is there a booster vacuum line, I don't see one.

YOUR FINE!
our throttle bodies are not the most "precision machined" pieces in the world.. if you hold the throttle body up to a light with it off the car and look at the clearance from the blade to the bore you see a small amount of light.
when you clean out all the carbon you clean carbon seal around the plate. so you actually have a small air leak. this is normal and will only last a week or 2 and then after that the carbon will build up again around the opening and seal the tb like normal..
nothing to worry about man

yes i would say from experiance its from the carbon not being there for your TB to seal up 2 and it will go away.... second carb cleaner and tb cleaner are the same thing( most say carb/tb cleaner together on bottle)

If you used paper towel maybe a little piece is stuck between the throttle plate and is holding it open slightly.
The positioner is zeroed soon as you turn the key to start the car and if a hair open will increase the idle .
You could try unhooking the battery to zero all the learned settings in the pcm and see if that helps.
