On my 98 SVT it has suddenly developed a very suttle vibration around 2300-2500 rpm. The only reason i noticed it is because thats the rpm i sit at on highway between 55 and 60. I was wondering if there was a throttle linkage spec. I dont know about manuals but in the auto vehicles i own when the linkage stretches a little it tends to cause the same problems. Any input would be helpful i'm pretty confused.
