What should my TPS voltage be with the throttle blade closed? and also at WOT what should it be?..I havent messed with it ever..and I got .78 closed and 5.55 volt's at WOT or 5.55 millivolt's..i dont remember Thank's,

WOT -- anything over 4.7 volts will throw a code, so try to get as close as possible with out going over.

TB closed -- I've seen anywhere from .45 - .9, currently mine is at .6

The Helm manual says the DTC goes set at 4.65 VDC at WOT so I set mine at 4.64 VDC. It says NEAR 0.6 VDC at closed throttle so I interpreted NEAR to mean it could be a slightly over or under that value. With a DIGITAL VOM you ought to be able to get "NEAR" 0.6 VDC. I used a tiny sewing needle on the blue wire of the TPS to pierce the insulation and run a jumper from the needle to the meter lead. This works great. Much better than that method of trying to put jumpers inside the connector to get your reading. Just get AutoTap for $350.00 and solve all those problems.

Hmmm. My Helms manual (2000) says 4.75+ volts sets the DTC.
Anyway, for my car, stock, the settings were .53V closed throttle, 4.36V WOT. After adjusting the TB butterfly to a 90* WOT angle, the WOT voltage was 4.60, as read w/a DVM through the TPS sensor.
Setting to a specific voltage is not necessarily the right thing to do,the idea here is to attain a 90* angle to incoming air to allow lesser resistance (just don't go over the voltage that trips the PO code).
As for my idle (closed throttle voltage), I have mine stepped up a little.

I have mine set at 4.68 at WOT and I don't have any SES codes. But I was told not to go beyond 4.7
