I have a 1993 4dr VW Jetta 2.0ltr
this morning I went to drive my car and heard a slight whistle it then went away.
after a few times of driving around I go to drive and at 2rpm I heard a whistling coming from the left side of the engine.(If im looking at it from the front) if im driving and I push in the clutch even though im at 30-40mph the rpms drop back down to 1rpm and there isn't a whistle. At idle it seems to be an ever slight whistling but at 2rpm and up it gets higher pitched. I was hoping I could do it yourself fix but if its more complicated then common sense I'd like to know what im gonna be looking at if I have someone fix it. Thank you any help is good help!
