Default help please! tb voltage...

I need to know what the voltage should be for the tb when it is sitting at idle. I had the idle screw turned up because it would cut out, and now i need to know what it should be at for "stock". Not wot, but when the throttle is sitting on the screw with pressure on the gas. Thanks!

At idle in Park and Drive/Neutral it should be 0.0 and no more than .4%

so, since i screwed it up a little to raise the idle, what should it be back down to? Its basically like i am giving it a little gas at idle, so i want it back down to where it should be. and suggestions on how high it should be? i dont want it to rev like it does turning on the car, and through shifts with no peddle pressure. thanks.

First, you need to lower the TB set screw to what it previously was, then you need reset the TPS.

You obviously need to lower the screw but it will NOT read 0 volts at idle. Should be somewhere between .55-.61V depending on what you have it set on. Once you adjust it you need to reset the TPS by:
take key out of ignition
unplug tps
turn key to on position and wait about 10 seconds
take key out of ignition
plug tps back in and you're done
