vibration in at all speeds

I have been tracking this site to try and get to the bottom of this problem.I have a 95 aurora with 113k. I have replaced the coils, wires, spark plugs, had my tires balanced,put injector cleaner in, and changed out the fuel pressure regulator. My hesitation went away the rough idle is gone the surging at low rpms all gone. http://a332.g.akamai.net/f/332/936/12h/www.edmunds.com/media/townhall/webxicons/emotorcons/emo_tongue.gif however a new problem has started. Anytime on acceleration my car really vibrates badly. No matter the temp. When I let off the gas the vibration goes away. I am running out of soultions to solve this problem I am hoping someone can help

Welcome to AF!

This sounds like a problem with the axle shafts. You probably have a cv joint going bad. Could be one or both sides. Have it checked by a mechanic or check it yourself but I would believe that this is your problem.

You may want to check Motor and Transmission mounts

I Know A Fair Amount About These Cars But I Am Unsure What I Am Going To Sugest Would Even Apply. Now That I Have The Disclaimed Out Of The Way, Could The Problem Be Related In Any Way To The Torque Convertor. I Believe That The Vibration Would Be Fairly Constant Though With A Convertor Problem. It Doesnt Hurt To Check The Fluid Anyway As A Quick Check. Usually If A Convertor Or Conv Clutch Is Bad You'll Be Spitting Metal Around And That Means Bad, Burnt Fluid. Like I Said I May Be Way Off.
