Well, heres an interesting one. To add to the continuing rough idle, Ive now noticed that, while in neutral and reving, the engine feels rough. Yeah, thats a normal problem, but it even feels rough while the revs are coming down. Thats kind of a new one to me?!
Any ideas what the hell is happening here? She doesent even have 50k miles on her yet, so I have no friggin idea... Help?

 

Now I know some of ya have an idea whats goin on here?

 

A few possibilities off the top of my head....TPS, vacuum leaks, MAP sensor, might need a tuneup (?)

 

^^What he said, but check the cat to make sure it's not clogged. But from your sign looks like it's fairly new.

 

Cat is new, tuneup is (always) fresh. Havent checked the MAP and TPS, not sure how you can really check a MAP. Just not sure why the hell it feels rough coming down as well...
