If you get it figured out I'd be interested in what you did. Pictures would be awesome if you have time but I know how you feel with school and work and not having any time.
Can you describe the rough idle a little more specific? Is it missin or idling up an down or what's it doing?
have you ever taken your vacuum hose off to put seafoam in? its exactly like that. thats actually what i thought it was to begin with. its not a miss.
