Car started idling lower than usual yesterday, around 500rpm which caused it to sorta shake like its going to stall but it doesn't. This is in park, neutral, and drive, everything btw. If I give it gas it seems fine and runs like a champ in top end so it doesn't seem to be missing or anything. The problem is only when I'm idle.

I took a poke around under the hood today after letting it sit all night and I think I found something disconnected from the throttle body but i'm not sure. Can anyone tell me what this is, if its disconnected, and if that could be the source of my problem?



I'm assuming the slotted piece connects over the nut on the throttle?

 

WEll if it runs good ide just go through and give it a good checking over maby look for vacuum leaks stuff like that maby a tune up while your at it? That cable looks like the one for the cruise control and dont suspect that as your problem. Maby it was holding your throttle open a hair or something but shouldnt have been.
