87 xj, 4.0 V6.....wait no just kidding.... inline 6 and a 5spd. When the tach reaches about 3000 RPMs there is a crazy/annoying/painful vibration in the dash. Any one had this issue or heard of it?

:confused: ran a 350 chevy in my 1972 4x4 had a strange vib. ended up being a broken blade on my fan :rolleyes:

im pretty sure its not in the engine compartment, it has got to be in the dash. i need to check tomorrow if it only happenes in gear or if it also happenes when not in gear....
