Bucking Hesitation Under Full Throttle
Well lemme Refraze that.
Under Half Petal Acceleration and Full.
IT bucks and Hesitates.
Areas that seem to be affected are in the area of 2K to 3.5K RPM and around 5 to 7K RPM
It feels like its possibly loosing spark or Fuel.. not sure.
Its got new plugs an Wires.
Problem is recent.
But im Completely Stumped.
Any help would be great

I agree with wvumtnbkr. I had a similar problem on my car. You have to check the resistance of the TPS while you slowly and steadily increase the throttle. If it's extremely jumpy then you have a problem. It's a difficult test to do because readings from multimeters take a minute to settle and it's hard to be super steady with the throttle.

Backprobe the green/red output wire and put the meter on VOLTS dc. Watch the reading as you move the throttle up/down. Your looking for *opens* or a reading that goes down as you depress the pedal and vice versa as you let off the pedal.
IF the car has been running good prior to this problem, then it's unlikely its the ECU grounds, since their under the upper intake manifold and would almost have to have been FOOLED with recently for them to go south.

Does the light go out when the sensor is disconnected?
Try that.
