There is a large misconception that Honda and Acura Throttle Position Sensors are "Riveted" in. This is false. Those "rivets" are actually screws with no head on them. You can either use a flat headed screwdriver and hammer to remove them, or you can cut a slot into them with a dremmel and unscrew them with a flathead screwdriver.
This is the "rivet-screw" that we are addressing.
THE HAMMER/SCREWDRIVER METHOD:
Get a good flat-headed screw driver that has a good edge on it. You need the good edge to dig into the screw material. Place the screwdriver at an angle in the position shown:
Tap the end of the screw driver with a hammer. The screw will rotate counter clockwise and loosen. You should be able to finish unscrewing it with the pad of your thumb. This way is kind of a pain.
THE DREMMEL METHOD:
Cut a slot into the "rivet-screw" Use a steady hand and cut carefully. Cut deep enough into the screw so that you can get a standard screwdriver blade into the slot.
Unscrew the critter.
RE-INSTALLING:
You don't want to re-use those crappy "rivet-screws". Go to the hardware/parts store and match the threads to a new, stainless metric bolt of the same size and length. If you have a Fast Idle Thermo Valve laying around, you can rob the screws from the cover plate, which is what I did.
Make sure the Plastic tab "A" fits into the slot "B" upon re-installation.
When you initially install the TPS (Throttle Position Sensor) It will be way-off.
Just turn it counter-clockwise untill the bolt holes line up.
Screw the bolts on finger-tight, plug it in, and whip out the multi-meter!
Start the car. With it Idling, Measure the voltage between the red and green wires. Adjust untill the voltage reads .45V at idle. Tighten those screws/bolts down! Re-check the voltage.
You're DONE!

***If your TPS is set from the factory, DO NOT ADJUST IT***
