I have the same problem and it's driving me up the wall. I have studied the forums closely for several months and this seems to be a chronic problem with some of the GT's. At times my Mustang will run smooth as a baby's ass but usually it bucks while following traffic at any speed less than 50.
If you find an answer please post it.

All of a sudden this seems to be a common problem with Stangs. It seems like a lot of people have ideas, but nothing seems to be working. I hope to replace my plugs today, if it doesn't rain.

I have heard and experienced this with other cars, that if you have a cracked spark plug, ie. tightening it down too hard, this will cause bucking or surging.
