Lt1 (need help!!)
I have a 1993 trans am and I just installed a 2 1/2" True dual set up w/ bullets dumped before the axle, and new poly motor and trans mounts. The problem i,m having is there is a really strong virbration right at 2000 RPMs. It,s smooth from idle all the way to 1900 RPMs and smooth from 2100 all the way to 6000 RPM, but the really vibrates strong exactly at 2000 RPM. Please Help!!!
