So a few months ago I installed BFI motor and transmission mounts and I got crazy vibrations through the cabin so after I put about a 700 miles on the mounts I figured I just change the engine mount and put it back to stock. So I installed the original engine mount (brand new). And I'm still get vibrations especially when the AC is on. Which I also experienced with the BFI mount. Can anybody please help me? These cabin vibrations are annoying..
