Default help again, please!

Just stopped in out of the shop for a min. The problem is vibration, when the car sit"s at a stoplight in neutral the whole car shakes, the steering wheel shake violently, it"s bad, at about 3500rpm it"s real bad. I believe it"s associated with the engine like I said it happens with the trans in neutral, nothing rotating but the engine. Any suggestions? thanks, now back to stereo installation.

Is it just idling poorly? Have you tuned it up recently?

It could be a bad motor mount.

With the lumpy cam she sounds pretty good, I did change the plugs, the wires are fairly new, the carb is rebuilt, and not much for vacuum problems, not a whole lot in that dept. Someone earlier did mention the motor mount , as far as the mounts go, is that something you can see with the engine in the car?, thanks again

put a jack under the motor and if a mount is bad it will lift up off of the frame
