RPM Bouncing on start & idle.
My 2005 A4 1.8t engine light came on last week then i noticed today that the revs are bouncing if im sitting still or will jump to almost 2000 rpm's when i turn it on, before i take it to a mechanic i would like to possibly know what it could be my first guess was the PCV.. but if anyone has some expertise or advice for this i could really use it.
