First off I wanted to say this is my first time here and im really new to the import scene, I was into mustangs and camaros but they always break down and eat up too much gas. Well I have a 90 4Door and my when im at idle, it goes from 2,000rpm and drops to 1000 then back up to 2000 it does this constantly, someone told me it could be my idle valve. I dunno im just hoping maybe one of you guys know wassup with this.
