1997 Gs idle problems need advise!!!

hi my girlfriend has a 97 gs eclipse 5-sp, n/a, im not very experienced in mitsubishi, but her car will rev up and down when at idle speed, the car runs fine just does that at idle, i know hondas better and i know that sometimes that is because of vtec, but mitsu doesnt have vtec so im almost clueless, it also could b the TPS? where is that? any links to pics? thanks for ur help!

check the plugs thats easy...and try cleaning the fuel injection that might work

Idle Surge...
see if this helps
