St-St-Studdering at take off.
The 951 seems to simply stutter at take off. If I just slam on the gas from a real real slow roll it'll stutter a tad before it goes. What usually causes a studdering take off other than motor mounts, because those were recently done.

Insure that your plugs, wires, cap & rotor are all in tip-top shape.
I found that low-rpm/high-load situations are the easiest place to see probs with the ignition system.
I'd look there first.
In addition, given that failure is relative common, the TPS sensor could also be a little flaky. Test it throughout the full range.

Tranny mounts are a more common source of stuttering. You can feel a slight "back/and/forth motion from the rear".

Did the car do this when you first bought it? You might have a fried clutch/warped flywheel. More than likely a failed motor mount. The passenger side seems to fail earlier due to the heat from the headers.

Craig,
I would look at the clutch, you might have broken the center in the clutch disc and under load it slips. We did the same thing in our racecar a couple years ago, thought it was the spiders in the diff at first but it turned out to be the clutch disc.
