To reset the computer back to it's factory settings disconnect the battery, have a cold one or 2, or just wait 10 minutes then hook it back up.

Not that I know of. Try disconnecting the throttle cable, maybe it is holding it open a little bit.

What is your manifold vacuum at idle? Do you hear any hissing sounds? Your question on the TPS(throttle position sensor) what is it where is it, it is located on the throttle body on the opposite side of the throttle cables.

To help determine whether or not it has a vacuum leak use a propane torch(unlit) with a hose attached and spray the propane all around the intake area. When it starts to idle the engine down with the added propane enrichment you will find where your leak is located. Also shoot some of the propane through the air filter intake, this will tell you if it is just running too lean.

The throttle body is easy to change,just four bolts.The throttle position sensor is on the throttle body itself.It has a couple of screws holding it in place and a couple of wires.If you have a stock cam,I would go no larger than 24lb injectors and maybe a 77mm mass air sensor.These things you can do yourself if you have tools and a guide.The ecm is the computer that controls the engine it is located on the passenger side kick panel.

Ever figure it out? If not, look for a big vacuum leak. My 5.0 T-bird decided it wanted to idle at 45-50mph with no power brakes any more. Turned out the cheezy little plastic vacuum manifold on the firewall inboard of the brake booster had a nipple broken off, causing a ~3/8" leak in the brake vacuum system. I fixed mine with a brass tee.
