1995 Cutlass Supreme

vibration at 40 to 60mph (only while accelerating)and also a little miss/rough on take off. I replaced all 4 tires and had them balenced also replaced rh CV shaft. Could this be CLOGGED Fuel injectors??. Just swaped out transmission too.Replaced plugs also.HELP!! :frown:

have you checked the front hub bearings? They will cause a vibration at a specific speed range just like an out of balance tire. Also check for a bent rim.

I can think of only one thing, In my olds. at the 100k mark, the engine mounts started going bad. It would do the same thing when I stepped on the gas only, replaced them, is fine now

hairo.

I had the dogbones (directly in front of the motor and easily accessible) replaced that hold the motor in place in the front. Shouldn't be hard to do with a crow bar and a friend.

Before that the rubber had shrunk and hardened and the engine would rock in the compartment.
