Well, 750 for auto trans, 850 for manual.
The TPS is best adjusted by voltage, not RPM though. The voltage is more accurate.

My idle screw WAS mucked with (a only a bit, it might appear?), and my TPS reads .5V at idle, can I safely mark my starting point and turn my screw a touch to bring it up to .9V? Or is this all too delicate for such a small increase? I've read that's .9V is goal starting read, but I ,like steve,want to be sure.

Adjust the TPS to get target voltage. Then adjust the screw to get the target RPM.
Adjusting the screw PROPERLY is a PITA. Takes about 20 minutes to go through the whole proceedure.
