JW, you don't need a special tool but you may find the screws holding the TPS to the Throttle Body are difficult to remove. I cannot speak for the 3.1 but on a 3800 the screws seem to be steel while the throttle body is aluminum, resulting in some corrosion and very tight screws. In addition, if you consider the end of the Throttle body, where the aircleaner duct attaches, to be a clock, the TPS is in the 8 oclock position, so it's not just a straight run in with a screwdriver.

I would recommend asking your NAPA or equivalent auto parts vendor, to show you what a new TPS looks like. Then you'll be able to easily identify it on the throttle body. Then I would recommend you use the trans dipstick to drip some hot trans fluid on top of the screws and do so for a couple of days in a row. You just want enough to allow the oil to work into the threads, don't flood the TPS itself. Then get a appropriate sized driver bit, so that the bit fits the head of the screw tightly. I have a set of assorted bits from Craftsman which fit into my 1/4 " socket on my 1/4 " ratchet wrench. Then I tap the back of the ratchet while exerting some pressure to turn the screw, trying to make sure to keep the bit straight and tightly seated in the head of the screw. That should work for ya.

BTW, I use a product called oxyguard, which is a grease that is designed to slow the oxidation between dissimilar metals, before replacing the screws. I got that at my local hardware store in the electrical supply section. It's good stuff.
