Ok so I have a mechanical question. In my 1999 gt when I accelerate you can hear a faint nocking. It only happens between 2500 and 3000 rpms. If I'm accelerating and hear it if I push down a little further on the gas it goes away. A mechanic told me it could be my timing gear and belt but he recommended a whole new engine soley because of my mileage (which is bull****) that's like 6 grand with labor. Does this sound like it could maybe be an issue?
