What is this?

Can someone please tell me what this is. I'm having the throttle issue and when looking at my truck I see this thing and a little cylinder down at the bottom looks like it should be resting fully but it's not. Is this normal?

That looks like the vacuum pot controlling the EGR flow valve. You're right, the bushing in the eyelet has failed causing a lot of play. Looks to me like it's causing the valve to be open a little more than it should, allowing some extra exhaust gas into the intake.

Thank you I'm gonna replace it today. I'm getting the electric throttle see dealer message. Maybe this will fix it
