Ok...not sure what it is, but I am hoping other people have experienced it.

03 Cobra....at low RPM's (1500-2200) under normal driving at sustained speed my car bucks at a evenly paced pulsing, but not violend fasion. Almost like I am driging down a road with waves in it. I would say it is equivalent to 1-2 per second.

Under acceleration and higher RPM it goes away....

Any ideas?

I have almost identical mods, and when my car had a slight surge it turned out to be my plug gap. I oprnrd up my gap to .036, and all was good.

Possibly clutch slippage

I had a similar problem, and I had water in the spark plug canals that was seeping through the threading when the engine warmed up. Just to be safe, i changed spark plugs and my problem went away.
