Knocking sound in drive just off idle, not reverse. Engine o

[Imiss#3]

I have an almost Buick, TTA 10k miles. I here a knocking noise as I touch the gas in drive, park or neutral. Brake torqueing a little also makes the sound for a second then it stops. It sounds like a brief spark knock. DS says no knock detected. In reverse it's nonexistent. Every time I touch the gas I hear it. High brake torque - no knock. Only as for a second when revving up off idle.
Engine mounts look good. Tranny fluid looks, smells good. No exhaust or other components touching.

Check the DriveShaft and ujoints...Inspect the differantal. Get under the car and have someone make the car make the noise while you listen from under the car....

Thanks Chris. Chris Rowe suggested the torque converter to flywheel bolts might be loose. He was right. Problem solved.
