it seems like it would be a breeze but would like some written info just to make sure i dont screw it up.

Well, taking it off is pretty easy. It is just 2 screws and you pull out. Putting on a new one and calibrating it is more of a pain in the ***.

When you install the new one you should not screw it in tight. Have it loose enough that you can rotate the tps assembly.

Some people like to just remember what position their old tps was and copy it. Then turn on the engine. If it is running crappy they start trying to nudge it one direction or the other to until it runs smoothly. This is pretty imprecise, but easiest to do.

The other, precise, way involes a multimeter, feeler guage, and a buddy.
For this way I'll just refer you to the following supraforums link.

It's for the gte, but its the same principle. I'm not sure if the number values are different for the ge motor.

The smallest nudge will change the settings significantly, so when you do calibrate it do so in very small incriments. Seriously, moving it a couple millimeters will change the resistance quite a bit.
