Ok, so first off I have a 97 Cobra that has a vibration at 1500 and 2500 rpm's, smooth before and after those two points. It happens not matter what, it can be in gear, out of gear, stopped, or rolling.
I Just replaced the harmonic balancer and didn't change a thing. The mods on the car are. o/r h-pipe, spin tech catback, tri-ax shifter, alum driveshaft, 4.10 gears, poly motor mounts, newish rubber trans mount. I never really noticed it until I installed a poly trans mount and the vibration was very noticeable, so I put the rubber back in. The only other thing I can think of is maybe changing the clutch??
Any input is welcome.
