The base idle is nothing more than the idle that the computer has learned at whatever angle your throttle body is set at when at idle. This technically shouldn't change by itself but it's always good to check it because you never know what the dealer or previous owner did to the car before you had it.
Once you change the setting of the base idle you will definately want toresetthe tps voltage

What is needed?
- Flathead screwdriver
- You'll also need a wrench to remove your battery cable

How to do it
1. Disconnect the battery's negative terminal to reset/clear the computer's memory. Leave it disconnected for 30 minutes. WARNING: Whenever removing your battery cables ALWAYS disconnect the negative battery cable first and reconnect it last. Otherwise you could destroy your computer or cause a battery explosion.
2. Disconnect the plug going to your idle motor which is located on the front of your throttle body.
3. Reconnect your battery's negative terminal.
4. Start the engine, and set the idle to the rpm you want with the stop screw on the bottom of the throttle body.
5. Turn off the engine.
6. Reconnect the plug on the idle motor
7. Make sure all accesories (radio, blower motor, a/c, lights, etc) are off and start the engine.
8. Let engine run for two minutes.
9. Turn engine off and wait two minutes then restart engine and let idle for two minutes with all accesories on.

im running a 347 stroker with a comp cams XE276HR (.544"/.544" 224°/230° @.050) 180 cc heads and a TFS TH intake on my STOCK COMPUTER with nothing more than a C&L MAF.

the 94-95 EEC troubles are GREATLY exaggerated (like joel said)

.... once the base idle reset is done, if the TPS voltage falls in the .6 - 1.0 vdc closed throttle range.... you do not need to readjust the TPS. A system keep Alive Memory (KAM) reset?.... yep. It will allow the system to relearn from the new setup conditions.

WHAT WIRES DO I USE TO CHECK THE TPS VOLTAGE
