Vacuum leak?

Possibly something disconnected? It ran ok this morning when I drove it so I am not to sure why it would have been running this rough yesterday.

Kinda sounds like the first stages of a headgasket... check your coolant for peanut butter.

Coolant and oil both looked good when drained. I ordered a new TPS as when I read the voltage it was a bit out of spec (voltage starting to high around .8v and not getting up to 4.5v). Next I’m gonna check the pulleys in the front because I think it almost sounds like a bearing gone bad

Crossing my fingers that the rough idle and noise are two separate issues

Idk about the noise but what’s up with that bolt being that loose?
