That part is called a dash pot dash pot. Whats missing on yours is the seperator, the filter and cap. As as far as i know you can`t get these parts seperatly, so you will need to replace it.

As far as I know, it's a dashpot, similar to the anti-stall dashpot on a carburetor. It serves the function of prolonging the throttle valve closing, for a slight lean condition when the throttle is released from higher rpm, helping to avoid a rich condition that could over time cause premature wear on the catalytic converter. Mine got to the point it would stick, holding my throttle open, and I would have to snap it open/closed to get my idle down. Annoying. So, went shopping and NO ONE knew what it was. Searched internet, found threads like this, got FSM, ID'ed part, went to store, way too much $$ for me. Took it off, and aside from off-throttle response being more jerky, no difference. It just idles down quicker. When I have the spare change, it'll get one put on it. So no worries, pop it off, or leave it on. But it can be a spendy little bugger. Long story short, There's millions of these trucks, with millions of issues, and a good search and FSM will almost always help you out.

niccee oka cool thanks man..I have a cap i noticed on mine his looks different..without it..it looks like the only thing it really does is something that connects with the gas pedal. cuz thats what the arm is for above is, but IDK.. You'll mostlikely be fine it looks like maybe the cap is for anticorrosion..But its just guess cuz I have no Idea what its for. Or what its purpose is

I think Toyota wanted about $60 or so, it might have been more. And all the local auto parts joints thought I was high when I said I was looking for the dashpot for a 22RE. "Huh? Fuel injected motors don't have one!" So I brought in mine and the FSM with location/description, and they still didn't know what I was talking about. Figured that a junkyard one would likely be in the same or worse shape, so I haven't replaced it.

Looks like the dash pot. There's supposed to be a small filter on the end of it. It's like a tiny shock absorber that prevents the throttle plate from snapping completely shut when you let of the accelerator abruptly (or even just lean off it)
Supposed to help with emissions by allowing better combustion at at idle. See here, even though this is for a MKIII Supra, the function is the same. You can click through the pages to read more.
